This was brought up in the Self Defence thread, but I feel it really deserves a thread of its own...I was just thinking about posting something on it anyway. <img border="0" title="" alt="[Wink]" src="wink.gif" />

Acrolein is made by removing 2 Water Molecules from Glycerol. It is a really nasty gas: highly flammable, very toxic, and causes some skin damage. It can also form explosive peroxides when stored. Here is an excerpt from its MSDS ( <a href="http://www.jtbaker.com/msds/a1538.htm" target="_blank">http://www.jtbaker.com/msds/a1538.htm</a> ):

In this book, it describes the synthesis of Acrolein by dehydrating Glycerol (100 gm) using a Potassium Bisulphate (80 gm) and anhydrous Sodium Sulphate (20 gm) and heating to 160-180 degrees celsius.

It also mentioned that other chemicals can be used to dehydrate the Glycerin, such as phosphoric acid or boric acid. As of right now, I only have Boric Acid (H3BO3) on hand. I also have 80% Glycerin on hand (The laxative kind..hehe). Using Boric Acid, I should only get 30-40% of the theoretical yields, but I think this will for the better. The impurities will make the Acrolein store better, since they will delay its polymerization. Once Acrolein has polymerized, it loses its irritating properties and is worthless. My problem is that I do not know how to figure out the ratio of 80% Glycerol/20% Water to 100% Boric Acid powder.

I'm interested in this because of its relatively easy synthesis, which would make it a good choice as an improvised Chemical Weapon.

EDIT- I realized this would be better in the "Battlefield Chemistry" section. Could a moderator please move it.
