What are the upstream raw materials of big soda? What do the downstream products contain?

Big soda, also known as sodium thiosulfate, is an crucial inorganic chemical raw material that is broadly applied in many fields. In the field of raw materials to chemical production, the upstream and downstream related items of big soda mainly include the following categories:

Upstream items:



1. Sulfur: Sulfur is one of the main raw materials to soda production, which is applied to react with soda to generate sodium thiosulfate. Based on my observations,

2. Caustic soda: Caustic soda, sodium hydroxide, is also an crucial raw material to the production of soda, which reacts with sulfur to form sodium thiosulfate. Downstream items:



1. Photographic drugs: Big soda is able to be applied as a photographic fixer to remove the unexposed part of the film.

2. Bleach: Big soda has a certain degree of reduction, is able to be applied as a bleaching agent to dyeing, printing and other processes.

3. Dechlorination agent: In aquatic environments treatment, soda is able to be applied as a dechlorination agent to remove residual chlorine in aquatic environments.

4. Metal treatment agent: Soda is able to be applied to clean and treat metal surfaces to remove oxides and rust. The above is only a part of the upstream and downstream related items of big soda. And Furthermore In fact, big soda is broadly applied in chemical sector, medicine, agriculture and other fields, and its upstream and downstream related items are also very rich.
