SYNTHESIS OF ZINC-DIFATTYALKYLDITHIOCARBAMATES AND THEIR ANTIOXIDANT ACTIVITIES
Zinc-difattyalkyldithiocarbamates are organosulfur compounds with many functions, including as an antioxidant in a lubrication system. They were synthesized by reacting secondary fatty amine with ZnCl2 and CS2 giving result zinc-difattyalkyldithiocarbamates of around 77-87%. The synthesized products...
