The manufacturing process of a reducing agent quu00ecmico the basis of SO2 and a reducing agent quu00ecmico the basis of SO2

摘要

The manufacturing process of a reducing agent quu00ecmico the basis of so ~ 2 ~ and a reducing agent quu00ecmico the basis of so ~ 2 ~, used as a substitute of conventional sodium bisulfite, and more specifically, said product obtained by chemical reaction of sulfur dioxide and caustic soda, estabil Izados stoichiometrically with the product of the chemical reaction between sulphur dioxide and ammonia, anhydrous.
