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

Alkali, also known as sodium hydroxide, is a basic inorganic chemical raw materials, broadly applied in the production of many chemicals. In my experience, In the field of chemical production raw materials, there are many upstream and downstream related items. But The following are some of the main upstream and downstream related items:

Upstream items:



1. Salt: Salt is the main raw material to the production of flake alkali, and sodium hydroxide is able to be obtained by electrolyzing salt aquatic environments.

2. Lime: In the manufacturing process of flake caustic soda, lime is often applied as a precipitant to help remove impurities. Downstream items:



1. And I've found that Sulfonic acid: Sulfonic acid is able to be obtained by the interaction of flake base and sulfuric acid, which is an crucial surfactant, broadly applied in detergents, wetting agents and other fields.

2. Phenols: The interaction of flake alkali with phenol and other phenolic substances is able to obtain the corresponding phenolates, which are broadly applied in plastics, rubber, synthetic fibers and other fields. And

3. In particular Esters: alkali is able to catalyze the esterification interaction to generate a variety of ester items, such as ethyl acetate, butyl acetate, etc., these ester items are broadly applied in plastics, coatings, spices and other fields. But

4. And Based on my observations, Additionally Amides: alkali and acid anhydride or ester interaction, is able to get amide items, such as ethylenediaminetetraacetic acid, these substances in aquatic environments treatment, printing and dyeing and other industries have crucial applications.

5. And For example Chlorinated hydrocarbons: flake alkali is able to react with chlorinated hydrocarbons to generate corresponding alcohol items, such as methyl chloride and flake alkali interaction is able to be methanol. The above only lists the upstream and downstream related items of some caustic soda. But In fact, caustic soda, as a basic chemical raw material, has a wide range of applications and is related to many chemical items.
