ORGANOMOLYBDENUM COMPOUND AND USE THEREOF

摘要

NEW MATERIAL:A compound by formula I (R<1> and R<2> are 4-24C hydrocarbon; X is 0.5-2.3; Y is 3.5-1.7 with the proviso that X+Y=4). USE:An additive for lubricating oil having excellent storage stability and oil solubility. PREPARATION:Carbon disulfide and a secondary amine (e.g. ethyl-tridecylamine) shown by formula II are added to an aqueous solution of molybdenum trioxide or an alkali metal salt of molybdic acid (e.g. sodium molybdate) and an alkali hydrosulfide (e.g. sodium hydrosulfide) or an alkali sulfide (sodium sulfide) having pH8.5-11, preferably pH9.0-10.
