Versuchsvorschrift
A solution of 87 parts of 2,4-dichloro-α-(chloromethyl)-benzenepropanol in 144 parts of concentrated sodium hydroxide solution and 350 parts of 2,2'-oxybispropane is stirred overnight at room temperature. The product is extracted with 2,2'-oxybispropane. The extract is washed with water, dried, filtered and evaporated. The oily residue is distilled, yielding [2-(2,4-dichlorophenyl)ethyl]oxirane; bp. 90°-98° C. at 0.01 mm. pressure.
