Detailed Description:
Cas No. :25322-69-4 Colorless to pale yellow viscous liquid. Not volatile. Non-corrosive. The molecular weight of general commodities is 400-2050. Lower molecular weight polymers are soluble in water. Higher molecular weight polymers are only slightly soluble in water, soluble in oils, many hydrocarbons, and aliphatic alcohols, ketones, esters, etc. The hydroxyl groups at both ends of the molecule can be esterified to generate monoester or diester. Its monoester is a non-ionic surfactant, and it can also react with alcohol to form ether. It is a solvent for vegetable oils, resins and paraffins. It is also used to prepare alkyd resins, emulsifiers, demulsifiers, lubricants and plasticizers. It is obtained by condensation of propylene oxide and propylene glycol in the presence of high pressure or acid catalyst.
