Abstract
The polysulfide formation reaction between epichlorhydrin, (ECH) and NaxSy was studied. As the result of consumption measurements of NaxSy in reaction system, it was proved that this reaction was rapid and easy. In a reaction at 90°C, the molecular weight of the product was large and the chlorine content was zero. In the case of a reaction with sodium polysulfide instead of sodium sulfide, a product with high content of sulfur was obtained. As for the effects of additives in the reaction system, with the exception of decrease in yield of product under addition of ethylenediamine, the addition of sodium hydroxide, organic solvents, phenol etc., produce small effects upon the yield, sulfur and chlor content of products, and the rate of this reaction. Comparative reactivities of ECH with the other dihalogenated compound were the same as that of ECH with, a, γ-dichloroglycerin to and were larger in the order of α, γ-dichloraceton, 1, 2-dichloroethane.
