Study on the synthesis and properties of ionic liquid lubricant additives
Three kinds of 1,8-diazabicyclic[5.4.0]undecane-7-ene(DBU)derivatives fatty acid-based long-chain ionic liquids were designed and synthesized,the oil solubility,corrosion and anti-wear and anti-friction properties of ionic liquids were investigated,the feasibility of these ionic liquids as lubricating oil additives was discussed.The results showed that the fatty acid ionic liquids derived from DBU had good oil solubility and no corrosion to copper sheet,at the same time,the anti-wear and anti-friction property of the oil can be improved.It provides a reference for the research and development of high quality addi-tives.
