Energetic derivatives of tetrazole


I'm finaly completed a compilation work on energetic derivatives of tetrazole, for this moment only in pdf version. Hope readers will find it interesting, you can get document by this link: Energetic Derivatives of Tetrazole Special thanks to The Davster for help with translaton&revision, and people who helped me to find required references in References section.

Anyone is welcome for any comments and suggestions. Regretably file is too large to attach it to post (endless upload loop), so i had to place it on rapidshare. If someone can tell me how to place it to forum ftp, please contact me via private message.

Wow- this is fantastic!
This looks like part of a PhD thesis! Minus the spelling errors :)
No detailed comments at this point but this looks very professional, it must have been a big effort writing this up!
Many thanks!

Here's your attachment url on the forum ftp where it resides now

http://sciencemadness.org/scipics/Energetic_Derivatives_Of_T...

The file size appears to exceed the limit allowed for attachments so you won't see the download count,
but you should still be able to get the file by the link,
and a lot faster download than from an attachment.

I posted this also in the related thread in Energetic Materials.

I read through many times, but I guess I missed a few:(

Great to be the first thing I see after not checking in for a while!
The final product looks great!

Anyone else having difficulty opening the pdf? I get "Bad encrypt dictionary" error, first time I've seen that.

Edit: From another forum.

"Your PDF is probably AES encrypted (introduced in PDF 1.6), whereas older versions only support RC4 and don't recognize AES (hence: the 'bad encrypt').

Either you change the encryption type, or you use the Reader versions that know understand AES."

Thus pdf wont open in Acrobat 6.0, need a later version.

No difficulty opening the file but it is encrypted and password protected .....an illusion of security actually,
shall I remove those and convert this to an unlocked document for easier reading :P ?

Thanks for comments, i can also upload pack of hi-resolution images, i haven't included them because pdf file size would be too large. Protection in pdf is not to block people from printing, it's to stop copy/paste avialability, so people cant' place text to other websites (at least in easy way). May be i've messed up somethere but pictures inside pdf look blurrish =( There are of course some spelling errors (i'm not native english speaker), so don't blame me much for that =)

It causes problems though for discussions where it is needed to excerpt specific parts for discussion. You can see that many places here in threads are excerpted parts
of articles and patents and references, we do it all the time. And it is aggravation to have to ghostscript and recompile an entire article to unlock it for an excerpt, knowing that if anybody was going to steal your work,
which is really a compilation of others work you couldn't stop them anyway.

About a month for original russian version, and 2 more weeks with english version.

One improvement I can suggest is to have "step by step" pictures of the procedures, otherwise an excellent write up.

Engager's Tetrazole Paper as pdf


The paper which Engager has shared with us has
been converted to a pdf which is more efficient for reading
and printing. Sorry for my being delayed in getting to this file conversion.
Here is the download link.

http://sciencemadness.org/scipics/tetrazoles(english).pdf

file is 8.89 MB and 31 pages Thanks to Engager for your excellent work

I posted this download link also in the thread in Energetic Materials entitled 5-ATZ(5-Aminotetrazole), the nitrotetrazolate ion and friends

Amazing! It indeed almost looks like a PhD thesis.

Did the diazotised tetrazole derivative explode once in solution? Or were you lucky? :P

Yes, it exploded, and more than once =)

I noticed in the section on the synthesis of 5,5'-Bis-tetrazolyl-hydrazine you mention using 50ml of 50% HCl.. Did you actually mean 50% HCl? I was under the impression that HCl of that concentration would boil at or below room temperature.. So I was just clarifying whether that was an error.

Heh, I bet that was exiting. How much damage did it cause if any?

Yes, this is a typing error - i meant 36% HCl (saturated water solution). Diazotetrazole readily explodes in solution, in concetrations above 2-3% exposions can be powerfull, and can easily destroy glassware, working with such concentrated solutions reqire use of shields for safety. Work with intermediate ammounts of diazotetrazole as in synthesis of 5-NT is much safer, in this case explosions are loud but are not particulary dangerous, but still can in some rare cases do some dammage to glassware.
