Propylene oxide CAS 75-56-9

Propylene oxide, also known as propylene oxide, methyl ethylene oxide, and 1,2-propylene oxide, is a very important raw material for organic compounds, and is the third largest propylene derivative after polypropylene and acrylonitrile. Propylene oxide is a colorless ether-odored liquid, low boiling point, flammable, chiral, and industrial products are generally racemic mixtures of two enantiomers. Partially miscible with water, miscible with ethanol. Forms a binary azeotropic mixture with pentane, pentene, cyclopentane, cyclopentene, methylene chloride. Toxic, irritating to mucous membranes and skin, it can damage the cornea and conjunctiva, cause respiratory pain, skin burns and swelling, and even tissue necrosis.

Propylene oxide uses:

Propylene oxide (PO) is the third largest propylene derivative after polypropylene and acrylonitrile, and is an important basic organic chemical synthesis raw material, mainly used in the production of polyether, propylene glycol, etc. It is also the main raw material for fourth-generation detergents nonionic surfactants, oilfield demulsifiers, pesticide emulsifiers, etc. The derivatives of propylene oxide are widely used in industries such as automobiles, construction, food, tobacco, medicine and cosmetics. Nearly 100 kinds of downstream products have been produced, which are important raw materials for fine chemical products.
