Chemical properties An additive polymer of polyethylene oxide and water. Molecular weight below 700, at 20ºC for colorless odorless non-volatile viscous liquid, slightly absorbent. The molecular weight between 700 and 900 is a semi-solid. The molecular weight of 1000 and above is light white waxy solid or flake paraffin or liquid powder. Soluble in water, soluble in many organic solvents, such as alcohol, ketone, chloroform, glycerol and aromatic hydrocarbons; Insoluble in most aliphatic hydrocarbons and ethers. With the increase of molecular weight, the water solubility, vapor pressure, water absorption and solubility of organic solvent decrease correspondingly, while the freezing point, relative density, flash point and viscosity increase correspondingly. It is thermally stable, does not work with many chemicals, and does not hydrolyze. Use gas chromatography to fix Chemicalbook liquid (maximum operating temperature 200ºC, solvent is acetone, chloroform, dichloromethane), separation and analysis of alcohols, ketones, aldehydes and other oxygen compounds, polytetrafluoroethylene water, fatty amines, volatile oil. It is widely used as a modifier for carrier and capillary column inner wall. Organic synthesis. Uses Used as analytical reagents, but also used in pharmaceutical industry for softener, lubricant and other purposes in medicine, cosmetics as a substrate, It is used as dispersant, lubricant, emulsifier and other organic synthetic medium in rubber, metal processing, pesticide and other industries. It is used as moisturizer for daily cosmetics industry, inorganic salt solubilizer, viscosity regulator and other purposes as flocculant, fluid antifriction agent, textile type infiltrating agent, retention and filtration aid, binder, thickener and denture fixing agent
