If you are lucky enough to ever find it:
NOTES on MILITARY EXPLOSIVES, Written by Erasmus Weaver (1909!) One of the 1st books published by Wiley (& Sons, Inc.) 382 pp Extremely well made,
was text book from Military Collage in Southern US.
Obtained was a 4th edition from 1918. dates of past editions were '09, '12', '17. All are beatifully bound in the old style of book binders fom the
past.
The book is a compendium of what was used as the military standard at the turn of the century and how they weere manufactured. Most of the primary
explos material is devoted to mercury fulminate but the techniques described are fantastic ("fulmination concepts")! Some of the little details are
worth every penny of the price of this collector's book. (It's available only through rare book dealers). There is a great deal of space devoted to
nitric esters and most of the materials are "garden variety" - HOWEVER, this is a well thought out volume with enough detail in manufacturing in it to
please a jaded reader. That is not to say it is not somewhat introductory but it has enough information on hand to make it more that an "intro" type
work.
What is most interesting is this is the period of histroy that words started to change in the sciences. One quickly notices the mixing of "nitre of
Barium" and related descriptions. Background on manufacturing is good, details on applied use of energetics (i.e. Blaster's Manual" type material) is
also well done. All in all it's damn interesting fom a historical perspective and there are tid-bits of good info available. ---- (Rare Book) special
order via Albris or Chatham Book Sellers.

I just got a copy of "The PENTAERYTHRITOLS" American Chemical Society Monograph Series, by Berlow, Barth, & Snow. 1958 Rienhold Publishing. - -
This was a tough one to get. Hard bound well preserved book that is nearly 50 yrs old. Very old library copy in fair condition. (Don't ask what it
cost...I collect this stuff  ).
Chapters deal with Preperation, physical properties, anayysis, oxidation, reduction, pyrolysis, reaction with inorganic reagents. Chapter on nitrates,
amines, halides, ethers, acetals, esters, etc. 17 in all. 300+ pages.
This is a older monograph series and containes most if not all of what someone would want to know regarding the compound if you plan on working
outside the given perameters of documentation. It -=IS=- almost 50 yrs old and is quite generalist in approach. but if one has little background (like
me) in solid alcohols this is wonderful. What I like the best is that the sighting at the close of each chapter gives patent references. What I liked
the least is that the notation is in a style typical of the 1950's.
If one has a yearning to know most all the uses of pentaerythritol in industry and the wonderful way it could be used in the future, this will be a
quick read. As a society the west uses possibly hunderds of tons of pentaerythritol a year (extrapolated from 1950's usage). There are various grades
of this material and it's availablity is enormous. Worth the time to hunt it down? Yes for a collector. Not a casual glance. Moderatly rare I believe.

No point scavenging for books. Just download an ebook with any P2P software i think this is illegal, though, and not reliable

If all people were like you there would be no ebooks! 
And good luck finding Paul W. Cooper "Explosive Engineering", Malvin E. Cook "The Science of High Explosives" or Per-Anders Persson "Rock Blasting and
Explosive Engineering" online. All I know is that Cooper's "Introduction..." has been scanned lately.
These are all in print, with editions from the last years, and can be ordered from your local book shop. Cooper cost me 20 bucks LESS than from the
ISEE site this way (IIRC 130$).
The biggest fun is getting old/rare books, e.g I have the complete Escales series sans "Black Powder". Want a PDF? It's the original German version
sorry!

Isn't there a religion versus science topic on Sciencemadness?
Personally I think the contents of the Bible are true.
But I see myself as a scientist too.
That's because science and religion, in my opinion, don't have to interfere with each other.
Have you read the entire Bible already?
If not: may I ask you what your opinion is based upon?
I would like to discuss about this, but maybe we have to start a new thread.

Experience tells me it is very difficult to discuss religion for the simple reason that you are a believer or not. It would be an equally pointless
discussion when it comes to which colour people like better. That is why these discussions usually end in a quarrel without any meaningful comments.
I'm quite sure these type of discussions can be generally found on the net, so I doubt SM is the right place...

Or how about the first world war that commenced exactly in 1914, as predicted by Daniël?
But we're getting a little off-topic now.
Let's discuss about the worst book again.

"Answers that start and end with GOD"? (with relation to the Bible). What about the Koran, claimed to have been ghost-written by Dog-Spelled-Backwards
(the false god of Islam), and claimed by Muslim suicide bombers as justification for going around killing as many other people and themselves as
possible, on promises of a free trip to Paradise with 72 virgins? That would surely make the Koran surely the deadliest book around; never mind
textbooks on explosives.

Shall we stop making a mockery of Islam? I don't like it if others make a mockery of my religion (Christianity), but then one also should not make a
mockery of other's religion.
Let's go back to the topic of pyrobooks and related stuff. There is already too much detritus in this thread.

But why be so sectarian , here's a hindu point of view _
" As i see it, faith is belief without reason . For those who believe, no explaination is necessary; for those do not, no explaination is possible."
-Verghese Kurien

Or perhaps that of a statesman of the English gentry
" A fanatic is one who can't change his mind and won't change the subject."

Legard had released a 3rd edition of the Preparatory Manual of Explosives. Legard has done quite a few of his "Preparatory Manuals" but the 1st and
2nd editions of the Explosives text had some glaring issues regarding his lack of accuracy siting the patents from which he drew from.
I have not had a chance to check if some of the sited patents were accurate (numerically, anyway) but he did add some items that made a well rounded
text. He uses LuLu's as a "per-unit" publisher and this is somewhat interesting. The use of LuLu's started during the release of the "Preparatory
Manual of Black Powder & Pyrotechnics" and some folks think that with the whole terrorism issue none of the smaller publishers want to risk
another "Hit-Man" law suite.
Quality-wise I wanted to comment that I enjoy the effort that he had put into his past projects. I don't think that he had always been satisfied with
them......I've never talked with him; but I think he could do better than some of his past efforts......he seemed rushed to completion....just my
opinion. The 3rd edition seems to be his best and if someone were to buy any of his books I would suggest that one as a starter as it's better
organized. The Pyrotechnics book was terribly organized, with one page or section seeming to end at the end of a page but really was continued on the
other side. THAT seemed like a rush job.

Nobody can probably blame you for expressing this opinion after the dreadfull things that happened in your birth country, though there are many
members on SM having other religions, who have nothing to do with the things that happened over there and would be seriously offended by your post.
Religion itself isn't bad because like with a gun it's eventually the individual that decides what to do with it...
SM really isn't the place for these kind of debates, so please stop provocating. It isn't helping anybody anyway...

I liked were this thread was going... Until I got 1/2 way down the first page.
I don't have any bad books to comment on, but I have a pretty good one, The Chemistry of Powder and explosives. I describes in great detail exactly
what is happening in the explosions of MANY different compounds, not only describing how to make them.

"DETONATORS, ELECTRICAL DETONATORS & PRIMERS for HIGH EXPLOSIVES": Hall, Howell, Taylor, Cope. - is a re-print of the USBoM working papers of
tests done at the turn of the twentieth century. The US Bureau of Mines had some extensive testing programs and some of their people developed some
mechanisms that are still utilized today. The value of this re-print is profound from both a historical and practical standpoint. The book is a
collection of USBoM bulletins that deal with both developmental data and material testing. The collection is subject specific and covers the major
detonators (blasting caps, etc) of the day. The chemicals utilized during this time were diverse as it was around 1906 that mercury fulminate was
found to be just too environmentally sensitive & toxic. Thus, there were those testing programs that dealt with some pretty strange primaries
(this may be where you can find actual testing of practical uses of the diverse picrates, HMTD, etc, etc).
Remembering that this was prior to numeric modeling and was basically a period of industrial applications of energetic chemistry (pre-WWI), the
material could be useful in
understanding some of the more complex studies of primaries today.
Don't look for this one to be scanned by some child and thrown around; it's not too easy to find. One issue that is troublesome is that there APPEARS
TO BE LITTLE ORDER TO THE PRESENTATION OF THE BULLETINS. There is some really interesting material here but it's hidden in the minutia of EXTENSIVE
sand-bomb and lead block testing.
It's a rather expensive book for what is essentially just re-prints of USBoM material ($65) but has some merit and is a great source for continued
searching through the Dept. of the Interior's now defunct Bureau. ..Worth a look.

in Chapter 20 where the preperation for ammonium chlorate is listed. NO WHERE in there is any caution listed for the sensitivity and unique issues
entailed in production of AC. Unfortunatly (including the amount of typos) spoiling a potentially good work. |
That's probably a good one to put up there. It gives a procedure that claims to produce copper fulminate from Cu(NO3)2 in HNO3 and EtOH.

In the course of a literature search I accidently came across this book with the strange title "Kings Chem Guide"
[email=]books.google.com.au/books?isbn=1411659236[/email]
Meeting statements such as
| Quote: | | enzymes have a particular attracation for substances like carbohydrates |
and, this very funny, explanation of fractional distillation
| Quote: | Distillation takes advantage of the vapour densities of the various components of gasoline. Vapours of liquid with lower densities will condense
higher up in the apparatus. The pentane fraction will condense at the highest mark due to its density being less than hexane ...
|
my initial thought was the author was a dabbler with no real understanding of chemical theory but with at least a good practical understanding. There
are excellent experimentalists like that.
However then I read the totally original account of PCl3 preparation below, where calcium and phosphorus exposed to oxygen for some reason unite with
each other rather than forming the far more energetically favourable oxides CaO and P2O5, which are some of the most stable oxides in chemistry, and
it seems the author never did what he is describing.
It appears the book is a flight of fantasy, a compilation of what the author imagined should work never having done the work, or understood the
theory. Possibly he picked up some gossip, read some stuff on the internet, balanced a few equations. The 'recepies' for a few drugs and pyro
precursors suggests his aim was at the clandestine and (tiny) amateur market. I have never seen anything like it. People often write misleading
rubbish but to have someone publish a whole book of the stuff must be some sort of record.
Here's one more joke, a caviat to the phosphide preparation in an open crucible with a bunsen burner

Below is a snapshot of a 'distillation' setup from Ledgard's Kings Guide to Chem - its very original - one never sees arrangements like that, its
interesting to find out why.
The author states the setup is based on a density differential. It is well known that vapours of higher density lie below those of lower density, for
instance chlorine vapours will stay inside an upright container open to the air for a long time because chlorine is heavier than air. So why doesnt
this distillation setup work?
When the gas mixture boils off from the liquid surface it is essentially a thorough mix of the ingredients, whats required is that they now segregate
on the way up according to density. Boyancy force drives the segregation, if the mass difference of two molucules is delM
F = delM g
For simplicity assume the height of the segregation vessel is H = 10cm. Then for ten atomic units mass difference the energy difference = force x
distance is
del E = delM g H ~ 10^-26 10 0.1m = 10^-26J
while the 1D kinetic energy with which the molecules are thermally agitated is
E = 0.5 k T ~ 3 10^-21J
the ratio of gravitational to thermal energy is about 300000!
Its clear no separation of any note will be achieved this way. A mixture of different density gases in the lab will stay a mixture!
The probability of finding a particle of energy E in an isothermal system is proportional to
e^-E/kT
so roughly the probability of a heavier particle being at the top rather than the bottom of such a segregation collumn is about
0.5 e^-delE/kT ~ 0.5 - 0.000001
so no difference at all!
The question arises why do gases segregate in the lab - CO2 for instance clings to the floor?
It seems the diffusion coefficients for gases are fairly small, and their viscosity sufficient so that convection predominates diffusion. A clump of
chlorine gas generated in a flask,will 'fall' to the floor due to convection arising from internal viscosity. But that is not the thermodynamically
stable state - eventually it will mix evenly with the air in the room.

Len1 you have explained what has long puzzled me: The conflict between these statements: "All gases mix to a homogeneous mixture" and "heavier gases
sink to the floor."
I, too, naievely I guess, thought that density was the driving force for the 2nd statement. So, are you saying too that a hot gas rises, as say in a
mirage, because the viscosity of the colder air is less?
A related observation also has puzzled me. Some observers have said that upstream air in a vent was contaminated by another gas introduced
downstream. I resolved this in my own mind as due to diffusion at the staionary boundary layer along the duct wall. Does this seem a reasonable
explanation?
Sorry for the off-topicness but I had to ask.
