PREPARATION AND INFRARED SPECTRA OF DIVINYL SULPHIDE, 2-METHYL-1,3-THIOXOLANE, AND 1,4-THIOXANE

Abstract

Dehydration of thiodiglycol at 195°–230° with potassium hydroxide produced a 36% yield of divinyl sulphide, 9–10% of 2-methyl-1,3-thioxolane, 7–8% of 1,4-thioxane, and 3.5% of vinyl 2-hydroxyethyl sulphide. Physical properties and infrared spectra are reported. Divinyl sulphide of high purity for polymer work was obtained by distillation in a Podbielniak column. Precautions that must be observed in the preparation, distillation, and storage are given.
