Properties and stability

Has good emulsification, dispersion, lubrication, softness, antistatic and pearlescent properties.

Storage method

Packed in plastic barrels. Store in a cool place.

Synthesis method

Put 0.95 mol of stearic acid, 1 mol of ethylene glycol and a catalyst amount of sulfuric acid into the reaction kettle. Heat and reflux, and continuously drain the generated water through the water separator. After 3 to 4 hours of reaction, take a sample to measure the acid value. When the acid value drops below 6 mg KOH/g, the esterification reaction is completed, and then the material liquid is poured into the neutralization kettle. , neutralized to an acid value of 4mgKOH/g. Drain the alkali solution, then use hydrogen peroxide to decolorize, cool and crystallize, centrifuge, filter, dry, and package to obtain the finished product.

CH2OHCH2OH+C17H35COOHCH2OOCC17H35CH2OH+H2O

Purpose

It can be used as emulsifier, dispersant, solubilizer, lubricant, softener, defoaming agent, antistatic agent and pearlescent agent, and is used in metal processing, fiber processing, cosmetics, detergents and pharmaceutical production.
