摘　　要：用三甲醇丙烷、季戊四醇分别与碳五至碳九的直链一元羧酸在微波辐射加热条件下合成润滑油类羧酸酯 ,并与常规合成进行了对照 .结果表明 :在微波辐射下反应时间大大缩短 ,合成速率提高到 10～ 15倍 ,该法操作简单 ,产物用1HNMR ,13Under rnicrowave radiation the esters of lubricating oil were synthesized by the reaction of 1, 1, 1-tris(hydroxymethyl) propane or pentaerythritol with C-5 to C-9 carboxylic acids. The results show that the reaction time under microwave radiation is largely shortened and the reaction velocity increases ten to fifteen times. This method is very simple, and the structures of products have been determined. by H-1 NMR, C-13 NMR and IR spectra.
