WERKWIJZE VOOR DE OMZETTING VAN AMMONIUMIMIDODISULFAAT, AMMONIUMSULFAMAAT EN AMMONIUMDITHIONAAT IN ZWAVEL- DIOXYDE EN AMMONIAK.

摘要

Ammonium imidodisulfate and ammonium sulfamate may be converted to sulfur dioxide and ammonia by heating them with a reducing agent or a catalyst in a bath of molten ammonium sulfate and ammonium bisulfate. The reducing agent is sulfur or a sulfur compound and the catalyst is selected from Mo, W, Cu, Fe, Co, Cr, Mn and Ni.
