2-Chloroethanol → 1-chloro-3-(2-chloroethoxy)propan-2-ol

A mixture consisting of 100 g 2-chloroethanol (12.4 mol), 573 g epichlorohydrin (6.2 mol) and 20 g of an acidic ion exchange resin were refluxed for 24 hours. The mixture was then filtered to remove the ion exchange resin and the excess alcohol and unreacted epichlorohydrin were removed by distillation. The residue was distilled under vacuum and the product 1-chloro-3-(2-chloroethoxy)2-propanol (804 g, 75% yield) distilled between 89 and 1° C. at 0.05 mm Hg.
