Abstract
Propylene oxide is produced by reacting a solution of peracetic acid in an inert solvent comprising mainly either acetic acid or a mixture of acetic acid with acetone or methylal with an excess of propylene, at a temperature in the range 30-80 DEG C. and at elevated pressure. Some propylene glycol monoacetate is also formed and this may be hydrolysed to propylene glycol, for example by a mineral acid and water or by ethyl alcohol. The propylene used as starting material may contain inert hydrocarbons, e.g. propane. The peracetic acid used may be obtained by the vapour phase oxidation of acetaldehyde with molecular oxygen. Specification 547,333 is referred to.
