Abstract
The synthesis of 1-propanesulfonic acid, 3-chloro -2-hydroxy sodium salt, and Oxiranemethanesulfonic acid sodium salt ,and their application for the functional materials were reviewed. Epichlorohydrin reacted with sodium bisulfite to produce 1-propanesulfonic acid, 3-chloro-2-hydroxy sodium salt which then produced Oxiranemethanesulfonic acid sodium salt in the alkaline solution by ring-closing reaction. Oxiranemethanesulfonic acid sodium salt acts as one kind of important multi-function matter because its molecular structure includes both the epoxy group and the hydrophilic sulfonate groups. Through the ring-opening and copolymerization of epoxy group, Oxiranemethanesulfonic acid sodium salt can be used to produce many functional materials with outstanding performance: gelling agent, gelatinizer, emulsifier, photosensitive material, Dye-protective agent and so on.
