Method for synthesizing 1, 3-dioleic acid-2-palmitic acid triglyceride

The invention discloses a method for synthesizing 1, 3-dioleic acid-2-palmitic acid triglyceride, which comprises the following steps: carrying out esterification reaction on glycerol and palmitic acid at 180-220 DEG C to generate tripalmitic acid glyceride; the method comprises the following steps: mixing tripalmitin, oleic acid and a catalyst under a certain frequency by utilizing microwaves, and reacting to generate 1, 3-dioleic acid-2-palmitic acid triglyceride; and carrying out reduced pressure distillation to remove unreacted oleic acid to obtain a triglyceride mixture. According to the invention, in the synthesis process of 1, 3-dioleic acid-2-palmitic acid triglyceride, a microwave or microwave-ultrasonic synergistic treatment mode is adopted, the content of OPO in the prepared mixed triglyceride is remarkably increased, the proportion of 2-palmitic acid in all palmitic acid is also remarkably increased, and the 1, 3-dioleic acid-2-palmitic acid triglyceride meeting the market requirements is prepared
