| Abstract: | In this paper, three types of complex esters lubricating base oils were synthesized under solvent - free system with trimethylolpropane, dicarboxylic acids and fatty acids. The influences of reaction temperature, vacuum, reaction time and molar ratio on the esterification were investigated based on the synthesis of complex ester of heptanoate. Physical properties of those types of products, such as viscosity index, flash point, pour point and oxidation stability, were tested, and the results show that they exhibit good performances. These kinds of complex esters could be used as lubricating base oils with excellent performances. |
