Monoglyceride purifying

Subject the epoxy resin to be purified to molecular distillation to obtain low total chlorine epoxy resin.

Glycerin monostearate (Glycerin monostearate, abbreviated as GMS), molecular weight 358, industrial products are usually yellowish wax-like solids or flakes, except for those containing monostearate In addition to esters, it also contains a small amount of diesters and triesters, which are tasteless, odorless and non-toxic. It is easy to emulsify with water and is a water-in-oil emulsifier. But because of its strong emulsifying properties, it can also be used as an oil-in-water emulsifier. It can be used as plasticizer, mold release agent, antistatic agent, lubricant, etc.

Production process:

glycerin and hydrogenated oil are subjected to esterification reaction and filtered to remove impurities, and the reaction solution is neutralized with sodium hydroxide to obtain a crude product. The crude product is subjected to membrane and two-stage molecular distillation to remove glycerol, free fatty acids, diglycerides and triglycerides, respectively. Glycerides, and finally obtain high-purity monoglycerides.
