CAS–No.: 7446–09–5

REACH Registration Number: 01-21194850-34-0024

Product description

Sulphur dioxide is a colourless gas with a pungent smell. It is soluble in water.The product has a heavily reducing effect. Aqueous solutions show an acid reaction. Sulphur dioxide is not combustible. The effect of oxidants such hydrogen peroxide and sodium hypochlorite an sulphur dioxide may lead to heavy reactions. Liquid sulphur dioxide is a good solvent for inorganic and organic substances.

Functional Uses

The sulphur dioxide is used as a disinfectant, anti-septic and anti-bacterial, such as bleaching agents and conservative of food products and the production of alcoholic beverages. Its applications still extend to the pulp industry, sugar mill, the flat glass manufacturing and special chemical industry in general and effluent treatment.

The product meets also the requirements for food industry (E 220) according to Commission Regulation (EU) No 231/2012 and to JECFA (2006).

Plain steel is suitable as a material for storage or transport containers. Since sulphur dioxide is a compressed gas the containers must be designed as pressure vessels.




Sulphur dioxide is classified as a toxic and non-flammable gas. The sharp odor and irritating effect on the mucous of respiratory apparatus and the eyes, permit to worn the presence of SO2, in quantity as low as 5 ppm.

Detection of sulphur dioxide leakage: gaseous SO2 instantaneously with ammonia forms an abundant white fog of ammonium sulphite. This way is easy to identify also minimum leakages in connection and pipelines by blowing gaseous ammonia onto suspected points, from a spray-diffuser containing 30% ammonia solution.

Do not allow the product to get into grown water, waters or sewage system in undiluted conditions or in large quantities.
