Bismuth dithiocarbamates and their use as additive for lubricants

Certain bismuth tris-(di-organic substituted dithiocarbamate) salts are useful as extreme pressure (EP) additives in oils and greases. The bismuth compounds have EP properties which are as good as or better than those of the corresponding analogous antimony compounds which have previously been sugge...

Zusammenfassung:Certain bismuth tris-(di-organic substituted dithiocarbamate) salts are useful as extreme pressure (EP) additives in oils and greases. The bismuth compounds have EP properties which are as good as or better than those of the corresponding analogous antimony compounds which have previously been suggested and used as EP additives in lubricants. Some of the bismuth compounds, particularly where the substitution includes C6 alkyl or longer, or branched alkyl groups, are novel compounds.
