Molecular formula: C3H8O2 Relative molecular weight: 76.09 Relative density :(20/20οC)1.0381 Appearance: Colorless hygroscopic viscous liquid, almost odorless. Boiling point: 188.2 Melting point: -59οC Ignition point: 421.1οC Viscosity (20 οC): 56.0mpa.s, Surface tension: 72.0 (25οC) Specific heat capacity (20 οC) 2.49kJ/(kg.οC), Heat of vaporization (101.3kpa) 711kJ/kg. Miscible with water, ethanol and a variety of organic solvents. Use: 1,2-Propanediol can be used as the raw material of unsaturated polyester resin. In cosmetic, toothpaste and soap, it can be used with glycerin or sorbitol as wetting agent. In tint, it is used as humidifying and levelling agent. Also used as antifreeze. It can be used in cellophane, plasticizer and pharmaceutical industry.99.9% 200kg/drum CAS No. 57-55-6 1,2-Propanediol99.9% Japan/Domestic 200kg/drumCAS No. 57-55-6Molecular formula C3H8O2 Relative molecular weight 76.09 Relative density (20/20οC)1.0381Appearance Colorless hygroscopic viscous liquid, almost odorless.
