Synthesis of phytostanyl esters of linolic acid by direct esterification without solvent
摘要
Abstract
To optimize the synthesizing of phytostanyl linoleate by direct esterification of phytostanols and linolic acid without solvent.With the esterification rate and oxidized degree as evaluation indicators, single factor exploration was performed to find out the suitable substrate molar ratio, catalyst dosage, reaction temperature and reaction time, and the optimal synthesis parameters were obtained after L9 （34） orthogonal design was adopted as the molar ratio of phytostanols and linolic acid was 3＂1 ,the catalyst was added as 3% ,reacted 5h at 150~C.The esterification rate of phytostanyl linoleate reached to 81.23%. Moreover, the phytostanyl linoleate was identified by TLC, HPLC and IR respectively,and its thermodvnamical orooertv was also studied.关键词
