Boas! welcome back to war! last night I talked about phosgene, IWW nervouse gas. Everybody started having ideas. Nothing is better, than to make it yourself . phosgene occurs when chloroform is decomposed as storage. What you need to do, is to prepare chloroform from calcium hypochlorite and acetone. Here's the cook receipt. So preparation of 28.6 g of Ca(ClO)2. Put the prepared bleaching powder in the flask of the apparatus pictured on pic.2. Also put there 75 ml of water. Put a mixture of 10 ml of water and 10 ml of acetone in the dropping funnel. The end of the dropping funnel must be lower than the level of liquid in the flask. Put 10 ml of water in the receiver to preserve the prepared chloroform from evaporation and to guarantee it's purification from acetone. Start introducing acetone drop by drop into the flask, heating the flak with the aid of a flask heater. If the reaction is too vigorous and the reaction mixture starts splattering into the reciever, heating of the flask should be stopped...any chemestry student does this for fun. REMEMBER WHEN STORAGE PHOSGENE NATURAL OCCURS ON THE TOP OF THE CONTAINER
