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

Upstream products:

1. Sulfuric acid: Sulfuric acid is one of the main raw materials for the production of iodine, which is used to convert the iodine element in iodine ore into soluble iodine salt.
2. Sodium hydroxide: Sodium hydroxide is also used in the production process of iodine, and sulfuric acid acts on iodine ore together to convert iodine into iodine salt.

Downstream products:

1. Potassium iodide: The reaction of iodine and potassium hydroxide can generate potassium iodide, which is an important chemical raw material used in the manufacture of drugs, photographic chemicals, analytical reagents, etc.
2. sodium iodide: iodine and sodium hydroxide reaction can generate sodium iodide, also used in the manufacture of drugs, dyes, analytical reagents, etc.
3. Organic iodine compounds: Iodine can react with many organic compounds to generate various organic iodine compounds, such as iodoform, iodobenzene, etc. These compounds are widely used in medicine, pesticide, dye and other fields.

In general, the upstream and downstream related products of iodine are very extensive, and the fields involved include medicine, pesticides, dyes, photographic chemicals, etc.
