Thiophosgene synthesis
WebBecause phosgene is a poisonous gas, many attempts have been made to substitute it with phosgene equivalents. The most common substitutes are diphosgene (DP; 15,159-9), triphosgene (TP; 33,075-2), carbonyl diimidazole (CDI; 11,553-3), disuccinimidyl carbonate (DSC; 22,582-7). WebMay 15, 1997 · Thiophosgene is manufactured on a mulittonne scale, using the continuous chlorination of carbon disulfide under aqueous conditions to prepare the key intermediate perchloromethyl mercaptan. The development of this process is described, and the uses of thiophosgene in the manufacture of chlorothioformates and isothiocyanates are reviewed.
