| Abstract: | Di-octyl-di-tridecyl pyromellitate is a base oil of luboil with high temperature resistance and other good properties. Di-octyl-ditrideeyl pyromellitate was synthesized with using non-acid catalyst. This process needs no washing and neutralization, and has no corrosion for equipment. The optimum reaction conditions are as follows： pyromellitic acid ： trdecyl alcohol ： octyl alcohol=1：2.2：3.6 （molar ratio）, esterification temperature and time is 220℃ and 2.5h respectively, the catalyst is 0.1% of total materials. The viscosity index and flash point of the product is 80 and 278℃ respectively. The yield of crude product is 95%. |
