To a solution of 27.2 parts of 2-propylphenol and 56 parts of 1-chloro-2,3-epoxypropane in 30 parts of ethyl alcohol, heated under reflux, was added a solution of 13.2 parts of potassium hydroxide in 50 parts of ethyl alcohol and 6 parts of water over 15 minutes and the mixture obtained was heated under reflux for a further 2 hours. The mixture was poured into 1,000 parts of water and extracted with ethyl acetate. The organic phase was separated, washed with water, dried over magnesium sulphate, filtered and evaporated to yield a yellow oil. The oil was distilled at the water pump to yield 31.0 parts of 1,2-epoxy-3-(2-propylphenoxy)propane, boiling point 155°-158° at 15 mm.
