Epichlorohydrin, sodium sulfite, propanediolsulfonic acidAbstract
The article studied the interaction of epichlorohydrin and sodium sulfite in contrast to the known reaction of epichlorohydrin with sodium bisulfite. It is known that the reaction of epichlorohydrin and sodium sulfite entails the formation of two products: 1,3 or 1,2 propanechlorhydrinsulfonic acids.
As the reaction proceeds, caustic soda segregates, and the reaction is accompanied by heat discharge. The process of interaction of epichlorohydrin and sodium sulfite was supervised as to the amount of alkali released, from the content of which we judged the degree of conversion of epichlorohydrin. With further heating of the reaction mass of epichlorohydrin and sodium sulfite products we observed the hydrolysis of the chlorine atom with the formation of 1,3-dihydroxypropanesulfonic acid. It was found that the optimum molar ratio constitutes 1:1 and maximum temperature constitutes 1000С. The yield of the reaction product was 99%, melting temperature was 3000С
