A demulsifier is a surfactant that breaks up an emulsion. The demulsifier mainly destroys the emulsion by partially replacing the role of the stable film. Used as a dehydrating agent, it can remove the water in crude oil and heavy oil, so that the water content can meet the requirements; it can reduce the viscosity of crude oil when used in oil wells, so that the oil wells will not be blocked. It is obtained by polymerization of fatty alcohol, propylene oxide and ethylene oxide. Soluble in water, light yellow or milky white viscous liquid. Soap smell. Freezing point 25 ~ 40 ºC. Hydroxyl value 60 mg potassium hydroxide/g. , the aqueous solution is milky white.
