Abstract
Disclosed are novel compounds prepared by reacting two moles of 2,5-dimercapto-1,3,4-thiadiazole and one mole of a hydrocarbon compound selected from terpenes, aryl compounds and aliphatic compounds which may be substituted by oxygen or oxygen containing groups. The hydrocarbon compound forms a bivalent radical linking together the two 2,5-dimercapto-1,3,4-thiadiazoles. The compounds are effective extreme pressure agents when incorporated into lubricating compositions.
