Sodium Hydrosulfite Production From Sodium Amalgam

This report entails the detailed cost evaluation of sodium hydrosulfite production from sodium amalgam. The preparation process begins with the chemical reaction between sodium amalgam, (obtained by the mercury cell electrolysis of sodium chloride solution) with sulfur dioxide in an alcoholic solution (such as methanol solution). The reaction results in the formation of sodium dithionite or sodium hydrosulfite as the final product.

Feedstock for Sodium Hydrosulfite

Sodium hydrosulfite is mainly prepared by using sulfur dioxide, sodium hydroxide, zinc dust or sodium amalgam as its major feedstock. The procurement of sodium hydrosulfite is determined by different factors, including the production cost of sodium hydrosulfite, along with the variations in its market prices, etc. Additionally, other crucial factors including the availability of its raw materials (including sodium chloride for the preparation of sodium amalgam, along with other raw materials such as zinc metal for zinc dust, which is further used for the production of sodium hydrosulfite), the demand for sodium hydrosulfite in the downstream industries (including textile, food, paper and pulp industries), along with the supply chain stability, logistics, trade, transportation, and governmental policies etc, largely influences its overall procurement across the globe.
