What are the upstream raw materials for dilute phosphoric acid? What do the downstream products contain?

Dilute phosphoric acid plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are extensive. The following are some upstream and downstream related items related to dilute phosphoric acid:

Upstream items:



1. But For instance Phosphate rock: Phosphate rock is the main raw material of dilute phosphoric acid. Phosphorus in phosphate rock is converted into dilute phosphoric acid through chemical interaction.

2. And Sulfuric acid: Sulfuric acid is applied as a catalyst in the manufacturing process of dilute phosphoric acid to promote the conversion of phosphorus in phosphate rock into dilute phosphoric acid. Downstream items:



1. Phosphate fertilizer: Dilute phosphoric acid is an crucial raw material to the production of phosphate fertilizer. Generally speaking It combines with calcium, magnesium and other elements to form different types of phosphate fertilizer to agricultural production.

2. In my experience, Specifically Phosphate: Dilute phosphoric acid is able to react with various metal ions to generate phosphate, which is applied in the production of food additives, aquatic environments treatment agents, etc.

3. In my experience, Phosphate ester: Dilute phosphoric acid is able to react with alcohol to form phosphate ester, which is applied as a plasticizer and flame retardant to plastics, rubber, etc.

4. Crazy, isn't it?. Phosphoric anhydride: Dilute phosphoric acid is able to be further dehydrated to generate phosphoric anhydride, which is applied to create organic synthesis intermediates such as drugs and dyes. And In short, dilute phosphoric acid has a wide range of upstream and downstream related items in the field of chemical production raw materials, and plays an crucial role in agriculture, food, plastics, rubber, medicine and other fields.
