Study On Tribological Characteristic And Synthesis Of Nitrogen Containing Heterocyclic Borate Ester
Abstract： This article synthesized Nitrogen containing heterocyclic borate ester studying the effects of reaction time, temperature, molar ratio to the production rate.It’s proved that rapeseed oil as a raw material esterified with methanol。Rapeseed oil diethanolamide: Boric acid: n-hexyl alcohol molar ratio of 1:1:1. The temperature is controlled at 120 ℃.The time is controlled at 6 hours.These are the most suitable reaction conditions which yield was 81.6%. We use four-ball friction tester to examine the tribological properties of the nitrogen containing heterocyclic borate ester in the base oil . Experiments show that the base oil containing 1.5% the nitrogen-containing heterocyclic borate ester is better in anti-wear performance. We made a determination of base oil, base oil adding 1.5% nitrogen containing heterocyclic borate ester and base oil adding the T202 to find the largest PB. The results show that base oil adding a nitrogen-containing heterocyclic has the maximum PB. Finally we made a determination of nitrogen containing heterocyclic borate ester compounding with T202. The results show when base oil adding 1.5% nitrogen containing heterocyclic borate ester complexing the base oil adding 1% T202, the anti-wear lubricants is best.
Keywords：Nitrogen containing heterocyclic borate ester, synthesis, anti-friction properties, tribological properties
