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

Iodine has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich. The following are some of the iodine-related upstream and downstream items:

Upstream items:



1. In particular Sulfuric acid: Sulfuric acid is one of the main raw materials to the production of iodine, which is applied to convert iodine in iodine ore into soluble iodine salt.

2. Sodium hydroxide: Sodium hydroxide is also applied in the manufacturing process of iodine. It acts on iodine ore together with sulfuric acid to convert iodine into iodine salt. Downstream items:



1. Potassium iodide: The interaction of iodine and potassium hydroxide is able to generate potassium iodide, which is an crucial chemical raw material applied in the manufacture of drugs, photographic chemicals, analytical reagents, etc. In my experience,

2. sodium iodide: iodine and sodium hydroxide interaction is able to generate sodium iodide, also applied in the manufacture of drugs, dyes, analytical reagents, etc.

3. But Organic iodine compounds: Iodine is able to react with many organic compounds to generate various organic iodine compounds, such as iodoform, iodobenzene, etc. These compounds are broadly applied in medicine, pesticides, dyes and other fields. In general, the upstream and downstream related items of iodine are very extensive, and the fields involved include medicine, pesticides, dyes, photographic chemicals, etc.
