Propylene oxide (PO) is a highly reactive chemical intermediate used, for the most part, in the manufacture of polyether polyols for urethanes, propylene glycols, glycol ethers, 1,4-butanediol, and polyalkylene glycols for a variety of chemical intermediates and functional fluids. Propylene oxide is the second-largest derivative of propylene, accounting for about 8% of global propylene market.

The unused methanol is recovered and recycled.2-methylpropene is obtained from a variety of sources:(i) From the and of various fractions from the .(ii) By dehydrogenation of 2-methylpropane, which is also formed as a by-product in various processes in the petrochemical industry. The vapour is passed over a catalyst (platinum and palladium on an inert support):(iii) Another route from 2-methylpropane involves its oxidation to 1,1-dimethylethyl hydroperoxide (often called t-butyl hydroperoxide:This process is carried out in the liquid phase, pure oxygen, under pressure, is passed through the liquid, which has been warmed to about 400 K.
Propene is then passed into liquid 1,1-dimethylethyl hydroperoxide under pressure at about 400 K with a soluble molybdenum salt as catalyst:Epoxypropane (propylene oxide) is a very valuable co-product and is used, for example in the production of polyols, used to make .The alcohol is dehydrated to 2-methylpropene, by passing the vapour over a catalyst:Ethyl t-butyl ether (ETBE) 2-ethoxy-2-methylpropane) is an alternative to MTBE as an oxygenate to enhance the octane rating of petrol.
