Recently I purchased some really special chemicals:

- SeO2
- Na2SeO4
- LiClO4
- SO3
- I2O5
- LaB6
- Cr(CO)6
- TiH2

All of them in fairly small quantities (tens of grams, 100 grams, that kind of amounts). To be used in small scale experiments, and some will be used as display samples as well.

The SO3 is ampouled in a beautiful ball-shaped ampoule, containing long needle-shaped crystals with a silky/soft appearance. It's appr. 50 grams and makes a beautiful display sample. It also is tempting, however, to use some for experiments. It's quite dangerous though and storage probably is a pain in the ass, once it is outside of its seal.

Chromium hexacarbonyl looks like fun. It also looks like it would be hard to prepare at home. Carbon monoxide at 280 atm anyone?

Much obliged - thank you. :)

It's amazing what one *can* actually buy on eBay these days - Chloral Hydrate, but no Ether, I'm guessing...


Meanwhile in the UK you will get arrested for carrying a potato peeler, saying mean things on the internet, and H2SO4 is now nearly impossible to find. However, you can buy kilograms of date rape drugs on ebay.

Welcome to regressive PC culture, where plugging the ears is #1 choice of dealing with reality.

You can't fix a problem till you actually listen and acknowledge there is one and its source(s)!

I went to a city with an Italian minority for some business I had there. In this city I found an Italian shop with some very interesting products: 10% HF, 10% HCl without soap and other junk (I couldn't find it in my town), 32% HCl (all fuming HCl I found in my town is both very expensive at 5 dollars a liter and could only be bought from some shady guy who had it from a long time ago) and pure NaOH (for some reason all I could find in my town was either very expensive or contaminated with 10-20% NaCl). I'm really excited to go home and do some fluoride chemistry :)

Nice finds, but be VERY careful with the HF. Even 10% HF can do a lot of harm if it comes in contact with your skin!

Yeah, I know. I plan to work with it using thick PVC gloves and safety glasses over a tray. Also, I will always keep baking soda and calcium chloride solution on hand when working with this acid so that I can neutralize a spill properly.

Cool. Have you seen UC235's yt video on this? Quite nice. Be prepared to sacrifice a flask though.

I have. My plan was to use a steel paint can as a flask with a copper coil wound through a bucket of water as a condenser, sitting on a layer of sand in a pie plate, heated with a camp stove. I can monitor the temperature with a laser thermometer to avoid excessive char.

I could run a stream of argon through the apparatus, but I am pretty sure that's not necessary.

Not a chemical acquisition, but I just ordered an empty 80 c.f. inert gas tank that I will get exchanged for a full 80 c.f. tank of either Nitrogen or Argon. :cool:

1.8 kg of dextrose. Also Petri dishes, which I am pretty sure are polystyrene. I constructed a polystyrene thermolysis device with a steel reaction vessel and a passively cooled copper coil condenser, but I'm not sure if I'll get to test it out this weekend.

I have been stockpiling NaOH (2kg 99% and 3kg draincleaner 90+%) as it may be difficult to buy soon in UK unless the soap-making community can do something.
---------------------------------------------------------------------------------
and
My garden was infested (invaded via my neighbours garden) with the weed 'mare's tail'/'Horsetail'
https://www.google.co.uk/search?biw=1093&bih=513&tbm...
which can grow beneath concrete slabs and weed membranes and a pond as far as the barrier exists !
It is an admirable foe that was around before the dinosaurs so is quite resilient to everything.
Glyphosate works but needs regular application and I'm not sure of the health implications.
Alkaline soil is my answer, achieved in extreme around the borders of gravel etc. NaOH definitely increases soil pH !
which kills and suppresses the little bast@&ds
NaOH is a little extreme as a pH modifier, but it is cheap.
(I tried dolomite first, but huge quantities and physical work would have been required)

IF you try NaOH as a weedkiller consider
the direction of the run-off of rainwater,
and how hot water gets when NaOH disproportionates,
and the fact that NaOH solution can burn your face off :o
(handle it with the same care as you would handle conc. sulphuric acid)
--------------------------------------------------------------------
A little bit of irony:
until recently the most 'dangerous' chemicals that I own were all OTC (changed due to EPP)
Sulphuric acid, Caustic Soda, hydrogen peroxide, chlorine-based bleaches and solvents/fuels.
The other chemicals in my 'chemistry set' need deliberate action to become dangerous whereas the OTC chemicals are intrinsically dangerous.
But my wife is still worries about me 'playing with CHEMICALS' :D

NaOH is one thing I can find in abundant quantity in almost every grocery store. I have never done this, but I can get 25 kg sacks of it delivered to my front door for just over $50 USD. I think people use it for making soap and biodiesel.

Sulfuric acid drain cleaners are harder to find. Home improvement stores have removed them, as have most department stores.

It is a very nice reductor. You can precipitate some metals from their salt solutions.
It's also a compound which can make LOTs of hydrogen.
As far as I know, in industry its most important application is as a reductor in organic chemistry, it is capable of reducing a -C(=O)- group to -CH(OH)- .

Arkoma,

Be sure to store your borohydride in a very dry environment. Storing it insider another tightly capped jar which contains a generous amount of dessicant works fine. Once the borohydride starts to absorb water it gets as hard as a rock. Also, weigh and transfer it rapidly as it quickly becomes "sticky" in moist air (like that found in Arkansas.)

Wait - all those ruined or used petri dishes I've been throwing away are polystyrene??? Noooo........ I've been stockpiling polystyrene goods for a while now, but have disposed of a lot of Petri dishes in my chemistry-unrelated endeavors (and in my microbio course, too, come to think of it).

I guess that explains why I was able to destroy my micro-well plate so easily, and a Petri dish as well, with the same stuff (BuOAc)...
