Solid Esters of Cellosolves and Carbitols

Abstract

Notes 1865 ml. of water. An excess (15.2 ml.) of thioglycolic acid6 was added and the mixture was heated to 100°with rapid stirring. When the solution became almost clear, it was filtered rapidly xvhile very hot. The filtrate was allowed to cool, and a copious crystalline precipitate formed immediately. The precipitate was filtered off and washed with three portions of 50 ml. of cold water. It was then dried to constant weight at 40°and then in a vacuum desiccator; yield was 18.8 g., 98%; m. p., 158-162°.
