摘要：

The chemical rearrangement reaction of beta- into alpha-monoglycerides is described. Four monoglycerides with different fatty acid chainlength have been investigated, and the equilibrium constant and the reaction velocity constants characterizing the reaction of the chemical rearrangement were estimated with a mathematical model. A 1:6.5 mixture of alpha/beta-monoglycerides appeared to rearrange to a mixture of 1:1 alpha/beta-monoglycerides within 24 h. Furthermore, the reaction velocity of the rearrangement reaction of beta- to alpha-monoglycerides depended on the fatty acyl chainlength in the monoglyceride.
