Glycerol as a starting material to prepare palmitate derivatives
MetadataShow full item record
Glycidyl palmitate, used to obtain high purity monoglycerides and epoxy resins, can be obtained from glycerol using a two-step process. The first step of this new approach consists in a reaction of esterification-chlorination of glycerol. An elimination reaction using Cs2CO3 allows the corresponding glycidyl ester to be prepared from the chlorohydrin ester intermediate.

Canela Xandri, Anna; Balcells Fluvià, Mercè; Villorbina Noguera, Gemma; Christou, Paul; Canela i Garayoa, Ramon (MDPI, 2020-05-28)Crude glycerol (C3H8O3) is a major by-product of biodiesel production from vegetable oils and animal fats. The increased biodiesel production in the last two decades has forced glycerol production up and prices down. ...

The method avoids using Crown-18 ether, which was needed to obtain ...
