Read： 1584 Time：28months ago Source：

propylene oxide is a colorless, low-boiling flammable liquid with ether odor. The industrial product is a racemic mixture of two optical isomers. Colorless volatile liquids have an odor similar to ether and are produced on a large scale in industry. Freezing point -112.13 ℃. Boiling point 34. 24 ℃. Relative density 0.859. Flash point <-37 ℃, refractive index 1. 3664. Viscosity (25 ℃)0.28mPa.s is partially miscible with water [solubility 40.5% (weight) in water at 20 ℃; Solubility of water in propylene oxide 12. 8% (weight)], miscible with ethanol and ether, and with dichloromethane, pentane, pentene, cyclopentane, cyclopentane, cyclopentene, etc. to form binary azeotrope.
