Synthesis of Glycerol Monostearate
Glycerol is generated as a byproduct in various industries such as soap manufacture industry and from biodiesel
production. It results in a continuous price drop of glycerol, and the storage of the surplus glycerol is an issue. Hence there are
new prospects to use glycerol as a raw material or convert them into the value-added chemical. Glycerol monostearate (GMS)
is synthesized from glycerolysis. In the present work, GMS is synthesized with a derivative of glycerol (1,2-O-isopropylidene
glycerol) with transesterification and deprotection reaction. The effects of the reaction molar ratio, temperature, time with
different heterogeneous catalysts were studied.
