A direct preparation of symmetrical saturated monoacid diglycerides is described. The synthesis involves the preparation of 2-O-benzylglycerol, acetylation, interesterification with either methyl stearate or methyl palmitate, and hydrogenolysis to yield the desired 1,3-diglyceride. The melting points of the symmetrical diglycerides are slightly higher than those obtained previously by other methods
描述了对称饱和单酸甘油二酯的直接制备。合成包括 2-O-苄基甘油的制备、乙酰化、与硬脂酸甲酯或棕榈酸甲酯的酯交换以及氢解以产生所需的 1,3-甘油二酯。对称甘油二酯的熔点略高于之前通过其他合成方法获得的熔点,这些方法涉及酰基的 1,2 至 1,3 位移。
