Preparation of chloroform-d

Preparation of chloroform-d

30 g of anhydrous calcium trichloroacetate are placed in a 100-ml flask and several small chips of metallic sodium added. 10 ml of deuterium oxide are added cautiously and the flask attached to the Dean-stark apparatus for automatic separation and return of the deuterium oxide.

A glass apparatus for the preparation of chloroform-d

The apparatus is fitted with a calcium chloride drying tube and a bulb to eliminate the effects of foaming which may occur toward the end of the reaction. The reaction flask is heated (oil bath) and maintained at about 125° C for 3 hours. During the decarboxylation reaction, 8.5 ml of chloroform-d are collected. After the removal of the chloroform-d, in order to recover deuterium oxide the bath temperature is raised and the remaining deuterium oxide removed. In this way 8.4 ml. of deuterium oxide are recovered. The yield of chloroform-d is 60% based on the deuterium oxide. The product is dried over calcium chloride and purified by distillation at 61.5° C.
