THE REACTION BETWEEN SODIUM SULPHITE AND SULPHUR.

Abstract

Some years ago, owing to the increasing magnitude of the chrome-tanning industry in India, it was decided to investigate the possibilities of the commercial manufacture of sodium thiosulphate in the country. Of the various reactions available for producing this substance, the one between sodium sulphite and sulphur appeared most suited to local conditions, and a few experiments were sufficient to show_ that the reaction took place with great ease and yielded a very satisfactory product. In view of these promising results, a small plant was constructed and used to produce sodium thiosulphate in appreciable quantities.
