Dumb Question:  Is it possible there's no chemical reaction, but the factory 
simply uses warm water, heats the stuff in the process of handling it, uses
heat to dry it out, etc?  It seems that all the water would do is allow the
gypsum to recrystallize under human control, allowing formation of shhets
instead of random chunks.

Just a naive guess.

Well, in ancient times, silver was the metal of the moon, as gold was
the metal of the sun.  And it was (is?) used to cauterize warts, if I'm
not mistaken. BTW, in Germany the old name of AgNO3 is "hell stone".

 Frankly, I expected this kind of response. It just happens to be a
reaction that interests me. I like organic chemistry because I LIKE it,
not because of alterior motives.  
 I still would like to know if anyone has some ideas. I know that the
Cannizzaro reaction (with KOH) will change an aldehyde into the potassium
salt of the acid of the corresponding aldehyde and benzyl alcohol as well

A more efficient reaction would be interesting.
 
 Oh yeah, those DEA guys just shrugged when I asked them... :-)

All very simple.  In alchemy, gold is the Sun and silver is the Moon.  So
'lunar'.  And caustic, because strong solutions can burn the skin.

You can use Clenbuterol for at least three reasons:
	- as an anti-asthmatic
	- to fatten calfs (which is illegal, at least in europe)
	- to dope athletes (which is illegal by international standards)

One of the athletics stars of the former GDR, Katrin Krabbe, will probably
be suspended for four years for taking Clenbuterol.  And though it is
technically incorrect to use the term 'steroid', I don't thinks it's
any better then that.  And it certainly has nothing in common with
vitamins.

Ah, methylene chloride, wonderful stuff. One of the cheapest solvents there is beside acetone and petrol. Between these three and water there's almost nothing you can't dissolve (including benchtops). 
We splash it around like it's going out of fashion. And word is - it is.
Along with carbon tet. and chloroform, dichloromethane is on the list of solvents on the 'ozone list' of chemicals to be phased out of use by the year x(?).
As for it's carcinogenicity - being fairly polar, it won't get stored in nocks and crannies like benzene or CCl4, and its pair of hydrogens give it lovely disposal handles. And remember, coffee contains around fifty organochlorines, of which about twenty nine are known to give you cancer. So does glucose.

Summary: Another form of polystyrene
Organization: Chinet - Public Access UNIX

Just free-associating, I thought of a different kind of polystyrene that
might make a nice classroom demonstration: popcorn polystyrene.  A recipe
that should work is to mix a gram of divinylbenzene with 100 grams of 
styrene and put in a 1 L vacuum flask.  Stopper the flask and replace the 
air with an inert gas (the only reason for the vacuum flask is that the 
easiest way I know to get rid of the air is to suck a vacuum and back-fill
a few times.  Set this on a shelf in room light.  Before too many days
have passed, things that look like popcorn will grow from the liquid.  The
rest of the liquid will gel, but stay transparent.

Brief exposure to modest amounts of styrene has never been shown to be 
harmful, and there's plenty of epidemiology to say that we'd know if there
was a major problem.  But avoid exposure as much as possible because 
there's no advantage to pushing your luck.  Styrene is very flammable, and
makes a smoky fire.  This demonstration is obviously not as dramatic as
the classic nylon rope, but there are fewer potential hazards than with
the classic recipes for that demo.

The history of popcorn polystyrene is interesting, but tracking it down is
up to you.  But guess what surprise people got when they first started
piping pure styrene around routinely.

If you in organic chem because you like it then surely you have more than one
reference source. The actual reactions are relatively simple, it is simply a 
matter of taking the time to figure out what the steps are. I had a similar

soy bean protein?
