What are the upstream raw materials for caustic soda? What do the downstream products contain?

In my experience, Caustic soda, also known as sodium hydroxide, is an inorganic compound broadly applied in the field of chemical production raw materials. Based on my observations, Its upstream and downstream related items are numerous, and some of the main upstream and downstream items will be described in detail below. And Upstream items:



1. Salt: The main raw material to the production of caustic soda is salt, which is able to be produced by electrolytic salt aquatic environments.

2. Coal: In some production processes, coal is applied as a heat source and raw material to provide electrical energy. Natural gaseous: In some production processes, natural gaseous is also applied as a raw material to heat and electricity. Downstream items:



1. Chlorine gaseous: When caustic soda is produced by electrolysis of salt aquatic environments, chlorine gaseous is also produced. Chlorine is able to be applied in the production of PVC, MDI and other chemicals. And

2. Sulfonic acid: Sulfonic acid is able to be prepared by the interaction of caustic soda and sulfuric acid. In fact Sulfonic acid is an crucial chemical raw material and is able to be applied in the production of detergents, lubriis able tots and other items.

3. Phenols: Caustic soda is able to react with phenol to create phenolates, and further react to generate various phenolic items, such as diphenol, methyl phenol, etc.

4. Paper chemicals: Caustic soda is applied as a cooking agent and bleach in the paper sector, which is able to enhance the condition and yield of paper. And

5. Soap and detergent: Caustic soda is able to be applied to create all kinds of soap and detergent, with good decontamination and emulsification. In my experience,

6. Food additives: Caustic soda is able to be applied to create some food additives, such as phosphate, citrate, etc. In short, caustic soda plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are numerous, involving many fields, such as papermaking, chemical sector, food and so on.
