実験手順
A mixture of 50 parts of [2-(2,4-dichlorophenyl)ethyl]-oxirane, 7 parts of ethanedioic acid, 300 parts of 1,4-dioxane and 150 parts of water is stirred and refluxed for 36 hours. The reaction mixture is evaporated. The residue is crystallized from 2,2'-oxybispropane. The product is filtered off and dried at the air, yielding 1-[2-(2,4-dichlorophenyl)ethyl]ethanediol; mp. 83.2°C.
