Sodium metabisulfite Usage And Synthesis

Description

Sodium metabisulfite (chemical formula: Na2S2O5) appears as a white crystalline or powder solid with a slight sulfur odor. It is toxic upon inhalation and can strongly irritate skin and tissue. It can be decomposed to release toxic oxide fumes of sulfur and sodium upon high temperature. It can be mixed with water to form a corrosive acid. It is generally used as disinfectant, antioxidant, and preservative agent as well as a laboratory reagent. As a kind of food additive, it can be used as a preservative and antioxidant in food. It can also be applied to the wine and beer making. Moreover, it can be used to sanitize the equipment of homebrew and winemaking as a cleaning agent. It also have various kinds of other applications, e.g. being applied to photography, as an excipients in some tablets, for water treatment, as a source of SO2 in wine, as a bactericide and as a bleaching reagent as well as reducing agent. It can be manufactured through the evaporation of a sodium bisulfite which has been saturated with sulfur dioxide. It should be warned that sodium metabisulfite has certain acute effects on the respiratory system, eyes and skin. In severe case, it can cause breathing difficulty and even pulmonary damage which finally leads to death. Therefore, effective protective measures and attention should be taken during the operation.

Uses

Sodium metabisulfite (SMBS, Sodium disulfite) is a white, granular solid sodium salt. an inorganic compound made up of sodium, sulfur, and oxygen, and used in many industries:

in the pulp and paper industry, in the photographic industry and in the various other industries as a bleach or dechlorinator.
Food Grade sodium metabisulfite may be used as a food preservative. It is also commonly added to various food products and wines as a preservative.
Sodium metabisulfite can also be used in the manufacture of other chemicals, Used in production of cleaning agents, detergents, and soaps.
It also acts as a corrosion inhibitor in oil and gas industry, as a bleaching agent in the production of coconut cream, as the source of sulfur dioxide and in the destruction of cyanide in commercial gold cyanidation processes.
Gold mining industry: It is utilized in the precipitation of gold from auric acid as well as in the waste water treatment to remove hexavaent chromium as trivalent chromium by precipitation after reduction.
Preservative in photo developer solutions, it is used in photography.
Oxygen scavenge:it plays as an oxygen scavenger to eliminate the dissolved oxygen in wastewater and in pipes.
Sodium metabisulfite may be used as an initiator during the cross-linking polymerization of polybutadiene in the cores of the vesicle membranes.
It may be added as an antioxidant during the preparation of stock solutions of 6-hydroxydopamine in various studies.
Dechlorination in municipal wastewater, pulp & paper, power, and textile water treatment plants.

Preparation

manufactures sodium metabisulfite by reacting sulfur dioxide with sodium carbonate (soda ash), purifying and drying to form crystals or powder.
Na2CO3 + 2SO2→Na2S2O5 + CO2
