Description

Propylene oxide (PO) is a clear colorless volatile liquid with an ethereal odor. The industrial products are the racemic mixture for two optical isomers. It can be partially miscible with water [the solubility at 20 °C in water is 40.5% by weight; water solubility in propylene oxide is 12.8% by weight]. It can be miscible with ethanol and ethyl ether and form a binary azeotrope with dichloromethane, pentane, pentene, cyclopentane and cyclopentene.

Usage

Propylene oxide is an organic compound with the molecular formula CH3CHCH2O. This colourless volatile liquid is produced on a large scale industrially, its major application being its use for the production of polyether polyols for use in making polyurethane plastics. It is a chiral epoxide, although it is commonly used as a racemic mixture.This compound is sometimes called 1,2-propylene oxide to distinguish it from its isomer 1,3-propylene oxide, better known as oxetane.
