PROCESS FOR PROCESSING VOLATILE SIDEPRODUCTS WITH PRODUCING PRECHLOROMETHYLMERCAPTANE

Perchloromethyl mercaptan is prepared with about 10% saving in raw materials by an improved process comprising (i) chlorinating carbon disulfide in the presence of iodine to produce a first chlorinated liquor, (ii) separating said liquor by distillation into a high-boiling fraction of technical-grad...

Zusammenfassung:Perchloromethyl mercaptan is prepared with about 10% saving in raw materials by an improved process comprising (i) chlorinating carbon disulfide in the presence of iodine to produce a first chlorinated liquor, (ii) separating said liquor by distillation into a high-boiling fraction of technical-grade perchloromethyl mercaptan and a low-boiling fraction, A, (iii) chlorinating fraction A in the presence of iodine and absence of any substantial amount of metallic halides to produce a second chlorinated liquor, (iv) separating said second liquor by distillation into a high boiling fraction of crude perchloromethyl mercaptan and a second low-boiling fraction, B, consisting essentially of sulfur dichloride, and (v) heating fraction B at about 90 DEG -150 DEG C in presence of a metallic halide to form sulfur monochloride and regenerate chlorine.
