Product Name：propylene oxide Molecular format：C3H6O CAS No：75-56-9 Product molecular structure：   Chemical Properties:  It is an organic compound with the chemical formula C3H6O. It is a very important raw material for organic compounds and is the third largest propylene derivative after polypropylene and acrylonitrile. Epoxypropane is a colorless etheric liquid, low boiling point, flammable, chiral, and industrial products are generally racemic mixtures of two enantiomers. Partially miscible with water, miscible with ethanol and ether. Forms a binary azeotropic mixture with pentane, pentene, cyclopentane, cyclopentene and dichloromethane. Toxic, irritating to mucous membranes and skin, can damage cornea and conjunctiva, cause respiratory pain, skin burns and swelling, and even tissue necrosis.   Application: It can be used as a dehydrating agent for the preparation of slides in electron microscopy. Occupational dermatitis was also reported while using a skin disinfectant swab. Chemical intermediate in preparation of polyethers to form polyurethanes; in preparation of urethane polyols and propylene and dipropylene glycols; in preparation of lubricants, surfactants, oil demulsifiers. As solvent; fumigant; soil sterilant. Propylene oxide is used as a fumigant forfoodstuffs; as a stabilizer for fuels, heat-ing oils, and chlorinated hydrocarbons; asa fuel–air explosive in munitions; and toenhance the decay resistance of wood andparticleboard (Mallari et al. 1989). Recentstudies indicate that the fumigant potentialof propylene oxide enhances at a low pres-sure of 100 mm Hg which could render it asan alternative to methyl bromide for rapiddisinfection of commodities
