两个羟基硬脂酸的合成及其对锂基润滑脂性能影响研究
|
摘要
以油酸、蓖麻油酸为原料合成制备了9,10-二羟基硬脂酸(DHSA)、9,10,12-三羟基硬脂酸(THSA)两种多羟基硬脂酸,其结构经~1H NMR、~(13)CNMR、FT-IR以及ESI-MS表征。分别以12-羟基硬脂酸(HSA)、DHSA、THSA为稠化剂原料,以癸二酸二辛酯为基础油,制备了三种锂基润滑脂。基础理化性能、摩擦学性能考察结果表明,DHSA、THSA所制锂基润滑脂具有更好的稠化能力、高温性能、胶体安定性和抗磨减摩性能。
9,10-dihydroxy stearic acid( DHSA) and 9,10,12-trihydroxy stearic acid( THSA) were seperately synthesized from oleic acid and castor oil acid,and their structures were characterized by~1 H NMR,~(13)CNMR,FT-IR and ESI-MS. Three kinds of lithium grease were prepared by using 12-hydroxy stearic acid,DHSA and THSA as thickening agent thickening agent materials and dioctyl sebacate as base oil.By investigating their basic physical and chemical properties and anti-wear and anti-friction performance,the conclusion was drawn that the lithium greases prepared with DHSA and THSA had better thickening ability,high temperature performance,colloidal stability,anti-wear and anti-friction performance.
