Synthesis and characterization of some novel silicon esters and their application as lubricant base stock solution

Abstract A series of functional organosilanes and their esters were synthesized by the hydrosilylation reaction of SiH group‐bearing organosilicon derivatives with maleic anhydride using Speier's catalyst and their esterification with long‐chain alcohols in the presence of stannous oxide. These products have been characterized using elemental analysis, FT‐IR, 1 H, 13 C and 29 Si NMR. Viscosity, density, pour point, flash point and tribological properties of these compounds have also been evaluated. These esters have a pour point of <−60 °C, a flash point of ∼200 °C (closed‐cup) and excellent load carrying capacity. Copyright © 2009 John Wiley & Sons, Ltd.
