ABSTRACT:
Thiadiazole derivatives characterized by the formula: ##EQU1## where R is hydrocarbyl of from 1 to 30 carbons and R' is hydrogen or hydrocarbyl of from 1 to 30 carbons prepared by the method of contacting a 2-amino-5-mercapto-1,3,4-thiadiazole characterized by the formula: ##EQU2## sequentially with an alkali metal hydroxide and a hydrocarbyl sulfenyl bromide characterized by the formula R-S-Br where R and R' are as heretofore defined. Hydrocarbon oil compositions comprising a hydrocarbon oil of lubricating viscosity containing between about 0.01 and 50 wt. % of said amino hydrocarbyldithio thiadiazole.
