something you'll want to investigate if you're developing organic phosphates or plasticizers, gasoline additives, or fire-resistant hydraulic fluids. A s a chlorinating agent, it neatly supplements and broadens your already wide choice of Hooker chlorinecontaining compounds. It's used also as a catalyst for intermediates and dyestuffs, a n d in preparation of médicinale such as sulfa drugs.

Well, one compound that meets these requirements is our lauryl mer captan—C12.4H25.7SH (average). And a strong advantage of lauryl mercaptan is availability. This product is one of many t h a t helped, in a modest way, to make war time synthetic rubber more plentiful. It's still around—still being used as a modifier in the synthetic rubber " h o t " process. W e can ship it in carboys, drums, o r b y the tank car. This is just one example of how checking with us might save you a cost ly development program, next time you need something new.

Often you can work with one of them more safely than with elemental chlo rine, and more conveniently than with elemental sulfur. Suifuryl cfiloride, SO2CI2, is a spe cial chlorinating agent for chlorophenol and other organic chlorides. It re acts with sodium salts of organic acids to form chlorides and anhydrides. It is of 9 9 + % pixrity. T/iiony/ chloride, SOCh, is a versa tile chlorinating agent, much used in preparation of organic acid chlorides. It may be used to introduce sulfur alone, o r in. combination with oxygen. You can get it in two grades: Technioal, 93% and Refined, 97.b%. For technical data on either, just check t h e coupon.
