Study on Tribo-chemical Properties and Synthesis of Oleic Diethanolamide Phosphate
Abstract:In vacuum condition, oleic acid diethanolamine was synthesized with oleic acid and diethanolamine, the molar ratio of 1:1, and petroleum ether as water-carrying agent. Through the three-step reaction of esterification, hydrolysis and neutralization, oleic diethanolamide phosphate(OEAP) was synthesized with phosphorus pentoxide as phosphorylation agent. The optimum synthesis conditions were established. Its structure was characterized by means of IR spectroscopy, and its friction performance was mensurated by using four-ball friction machine. The optimum synthetic conditions about oleic diethanolamide phosphate were oleic diethanolamide: phosphorus pentoxide=1:1(mol•mol-1) , the temperature of reaction was 80℃ , and time of the reaction was 4h. The determination of friction properties , on results , it is showed that when the content of oleic diethanolamide phosphate is 1.5%(wt%), the anti-wear is the most suitable. To determine the largest non-card bite load PB of base oil, adding 1.5%(wt%) of oleic diethanolamide phosphate in the base oil and adding the T202's base oil. On results , it is showed that PB of the base oil after adding T202 and PB of the base oil after adding oleic diethanolamide phosphate is so closed. Finally, to determine the friction chemical about the compound of oleic diethanolamide phosphate and T202 , the friction and anti-wear performance impact of these two adding amount of base oil, on results , it is showed that when add 1.5%(wt%) of oleic diethanolamide phosphate and add 1%(wt%) of T202 synergied , the anti-wear of lubricating oil gains it’s the best effects.
