S-Triazine derivatives as multi-functional additives for lubricating oils

摘要

Disclosed are lubricating oil compositions containing from about 0.01 weight percent to about 5 weight percent of oil-soluble multifunctional additive having the general formula ##STR1## where A. X. sub.1 is --S--CS-- OR, --S--CS--NR.sub.2, --S--PS--(OR).sub.2, or -- O-- P(OR).sub.2, and X. sub. 2 and X.sub.3 are chlorine, bromine, --S--CS--OR, --S--CS--NR.sub.2, - -S--PS--(OR).sub.2, --OP(OR).sub.2, or R; orP PB. X.sub.1 is --S--CS--OR, --S--CS--NR.sub.2, --S--PS--(OR).sub. 2, or --O--P--(OR). sub.2, and X.sub.2 and X.sub.3 are chlorine, bromine, --S--CS--OR, --S-- CS--NR. sub.2, --S--PS--(OR).sub.2, --O--P--(OR).sub.2 or --HN--R'P P where R comprises hydrocarbyl groups or chlorine, bromine or hydroxy substituted hydrocarbyl; and R' comprises hydrocarbyl, or hydroxy, amine or amide substituted hydrocarbyl. The lubricating oil compositions have improved extreme pressure, dispersancy or anti-oxidant properties.
