Propylene oxide is a very important raw material for organic compounds. It is a colorless ether liquid. It has a low boiling point and is flammable. Partly miscible with water, miscible with ethanol and ether. Propylene oxide is mainly used in the production of polyether polyols, propylene glycol and various non-ionic surfactants.

1. Used in organic synthesis and plastic manufacturing. Also used as a solvent and chromatographic analysis standard.

2. Propylene oxide is an intermediate of the herbicide metolachlor.

3. Propylene oxide is an important organic chemical raw material. It is the third largest product of the propylene series. The biggest use is to make polyol (polyether). And then to make polyurethane. In the United States and Western Europe, each accounted for 60% And more than 70%.

4. Propylene oxide is used to prepare non-ionic surfactants and allyl alcohol. Propylene glycol, isopropanolamine. Propionaldehyde, synthetic glycerol. Organic acids, synthetic resins. Foam plastics, plasticizers, emulsifiers, wetting agents. Detergent, bactericide, fumigant.
