Under 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.
