HCID 24699MonostearinYield 80.9%

Procedure

The experiment was carried out under the same conditions as in Example 3 but using a molar ratio of glycidol:stearic acid of 1.3:1. After 3 hours the amount of glycidol equivalent to the stearic acid had reacted and the mixture was cooled and worked up in a manner analogous to Example 1. There were obtained 116 grams of monostearin (80.9% yield) with the following properties:
