Sulfur dioxide is an intermediate in the production of sulfuric acid,

being converted to sulfur trioxide, and then to oleum, which is made

into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur

combines with oxygen. The method of converting sulfur dioxide to

sulfuric acid is called the contact process.

SO2 gas purity we provide:

1.Precursor to sulfuric acid

Sulfur dioxide is an intermediate in the production of sulfuric acid.

being converted to sulfur trioxide, and then to oleum, which is made

into sulfuric acid. Sulfur dioxide for this purpose is made when

sulfur combines with oxygen. The method of converting sulfur

dioxide to sulfuric acid is called the contact process.

2.As a preservative

Sulfur dioxide is sometimes used as a preservative for dried

apricots, dried figs, and other dried fruits owing to its antimicrobial

properties, and it is sometimes calledE220 when used in this way.

As a preservative, it maintains the colorful appearance of the fruit

and prevents rotting. It is also added to sulfured molasses.

3.In winemaking

Sulfur dioxide is an important compound in winemaking, and is

designated as parts per million in wine.

Sulfur dioxide exists in wine in free and bound forms, and the

combinations are referred to as total SO2.

4.As a refrigerant:

Being easily condensed and possessing a high heat of evaporation,

sulfur dioxide is a candidate material for refrigerants.
