Mono Propylene Glycol(MPG) CAS: 57-55-6

CAS: 57-55-6

Polypropylene glycol is a polymer with the formula H(C3H6O)nOH, a colorless to yellowish viscous liquid. Non-volatile. Non-corrosive. The molecular weight of general products is 400~2050. Lower molecular weight polymers are soluble in water. The higher molecular weight polymer is only slightly soluble in water, soluble in oil, many hydrocarbons and aliphatic alcohols, ketones, esters The hydroxyl groups at both ends of the molecule can be esterified to form single or double esters. Its single ester is a non-ionic surfactant and can also interact with alcohols to form ethers. It is a solvent for vegetable oils, resins and paraffins, and is also used in the preparation of alkyd resins, emulsifiers, deemulsifiers, lubricants and plasticizers. It is prepared by condensation of propylene oxide and propylene glycol in the presence of high pressure or acidic catalyst.
