Product method of Glyceryl Monooleate Liquid

1. Chemical synthesis method

‌1. Direct esterification method‌
Glycerol and oleic acid are heated and reacted under the action of acidic (such as sulfuric acid, hydrochloric acid) or alkaline catalyst (such as sodium hydroxide) to produce a mixture of monoolein, diglycerol and by-products, which needs to be purified by molecular distillation

‌2. Hydroxyl functionalization derivatization method‌
Using monoolein as raw material, carboxylic acid groups are grafted with maleic anhydride through esterification reaction, and anionic surfactants can be further synthesized.

2. Enzyme catalysis (green process)

‌1. Solvent system optimization‌
‌Tertiary butanol system‌: Novozym 435 lipase catalysis, substrate molar ratio (glycerol: oleic acid) 1:3, 50℃ reaction for 8 hours, monoglyceride yield 71.35%.
‌Mixed solvent system‌: tertiary butanol/isopropanol (80/20, v/v) can reduce the melting point to 6.9℃, and the monoglyceride yield is increased to 75.31%.

‌2. Continuous production‌
The packed bed reactor (PBR) continuously catalyzes the glycerol hydrolysis of tea seed oil. When the feed rate is 0.25 mL/min, the monoglyceride content reaches 80.74% and the production capacity is 0.698 kg/(kg enzyme·h)
