What is Propylene Glycol CAS 57-55-6?
The substance corresponding to CAS 57-55-6 is Propylene Glycol, a colorless viscous liquid with a chemical formula of C3H8O2, also known as Propane-1,2-diol. It is almost tasteless and odorless, hygroscopic, and miscible with water, ethanol, and a variety of organic solvents, but insoluble in petroleum ether and paraffin.
The melting point of pg is -60°C, the boiling point is 184-189°C, the density is 1.036-1.040 g/cm³ (20°C), and the flash point is 99-107°C. In terms of chemical properties, as a diol, it can undergo esterification, etherification, oxidation and other reactions, react with fatty acids to form propylene glycol fatty acid esters, and react with ethylene oxide to form polypropylene glycol.
