摘要

Abstract

A new kind of silicon-based biological lubricating base oil with good viscosity-temperature behavior

viscosity index

thermostability

oxidation stability and wear resistance performance was synthesized as a derivative of methyl oleate. Trimethylsilylation reaction was introduced to further improve methyl oleate oxidation stability and lubricity after epoxidation and open-ring reactions. The order of effectiveness of acid binding agent was

-diisopropylethylamine (DIEA) pyridine diethylamine triethylamine

and the effects of various parameters on the trimethylsilylation reaction as well as on the silicon-oxygen bond stability and reaction yield were studied. A maximum yield of 34.54% was achieved at hydroxyl/trimethyl chlorosilane/DIEA molar ratio of 1:1.25:1

reaction temperature 40℃

reaction time 1.5 h.
