SODIUM SULPHIDE FROM SODIUM SULPHATE
[EIRI/EDPR/9031] J.C. 464
INTRODUCTION
Sodium sulphide, Na2s is an organic chemical that has attained as very important position in the organic chemical industry.
It is an important sulphide of sodium. It is widely used in leather industry for removing hairs from the hide. It finds extensive applications in textile and also synthetics of sulphur dyes and reduction of amino compounds. It is also used in paper industry, lothogrraphy and engraving manufacture of sulphur black dyes etc.
There was no production of sodium sulphide in India before the war, all the requirements being met from imports. Arrangements for the import of sodium sulphide failed and considerably difficulty was experienced by the textile and terming industries in meeting the requirements of the deffence serious for textiles and leather. The question of developing the sodium sulphide industry in India became urgent and was immediately taken up. Shortly before that time extensive deposits of sodium sulphate from which sodium sulphide is manufactured. The smaller producers either obtained sodium sulphate which left over as a by-product in the manufacture of bichromates or hydrochloric and nitric acids or Rayon industries, as in most foreign countries. There was no control over either production of sodium sulphide or its distribution or its price during war time.
