Abstract

1410546 Purification of propylene oxide HALCON INTERNATIONAL Inc 28 June 1973 [28 June 1972] 30825/73 Heading C2C Propylene oxide, which is contaminated by paraffinic and olefinic hydrocarbons is purified by extractive distillation with a monocyclic aromatic hydrocarbon having 6-12 carbon atoms and a melting point below 50‹ C. and recovering propylene oxide as a distillate. Suitable aromatic hydrocarbons are, for example, benzene, toluene, ethyl benzene, o-, m- and p-xylenes; cumene, pseudocumene, mesitylene, p-ethyl-, n-propyl-, n-butyl- and t-butylbenzene; p-cymene; 1,3,5-triethyl-, 1,2,3,4- tetramethyl, 1,2,3,5-tetramethyl-, n-amyl-, 1,3-diethyl, and 1,4-diisopropyl-benzene; and 3,5-diethyltoluene. The contaminated propylene may be obtained, for example, by oxidizing propylene with an aromatic hydroperoxide and the corresponding aromatic hydrocarbon may be used as the extractive solvent in the distillation step.
