Rapid Synthesis of Palm-Based Monoacylglycerols

摘要

Rapid synthesis of high-purity MAG from refined,bleached,and deodorized palm stearin(RBDPS)via chemical glycerolysis in the presence of pyridine was developed to obviate the conventional molecular distillation in the production of pure MAC.The optimal reaction for the sodium methoxide-catalyzed glycerolyis of RBDPS was recorded at 110 deg C using a 3 wt% catalyst concentration based on the weight of RBDPS,with an RBDPS/glycerol ratio of 1:2 and an RBDPS/pyridine ratio of 1:4.High yields of over 99% were achieved rapidly in 15 min,and increases in DAG and FFA were observed after a prolonged reaction time.
