Sulfur Chloride (sulfur monochloride, S2Cl2, CAS 10025-67-9) is a yellow to amber fuming liquid with a choking odor, a specific gravity of about 1.6 to 1.7 and a boiling point near 280°F (138°C). It reacts violently with water, releasing hydrogen chloride, sulfur dioxide and sulfur. It is used in rubber vulcanization, lubricant additives, insecticides and chemical synthesis. Tanks must be dry, sealed and protected from moisture. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Nylon is the most economical tank material for Sulfur Chloride, rated Excellent. PVDF (Kynar®) is also rated Good or better. Avoid Buna-N and EPDM gaskets; 316 stainless steel and aluminum hardware. Rated Fair (contact us before use): HDPE and polypropylene tanks; HDPE, PVC, CPVC and polypropylene fittings.
