Dimethyl sulfoxide (DMSO) is an important chemical raw material, which is widely used in medicine, pesticide, chemical fiber, petroleum processing and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of dimethyl sulfoxide mainly include the following categories:

1. Upstream product

The production of dimethyl sulfoxide mainly uses dimethyl sulfide as raw material and is produced by oxidation reaction. Therefore, dimethyl sulfide is the main upstream product of dimethyl sulfoxide. In addition, the production process of dimethyl sulfoxide also needs to use the catalyst, oxidant and other auxiliary raw materials, such as hydrogen peroxide, sulfuric acid and so on.

2. Downstream product

dimethyl sulfoxide as an excellent solvent and chemical intermediate, its downstream products are very extensive. The following are some of the main downstream products:

(1) Pharmaceutical intermediates

dimethyl sulfoxide can be used as pharmaceutical intermediates for the production of a variety of drugs, such as antibiotics, anti-cancer drugs. In addition, dimethyl sulfoxide can also be used in the preparation of drug carriers, drug solubilizers and the like.

(2) Pesticide intermediates

dimethyl sulfoxide can also be used to produce pesticide intermediates, such as pesticides, fungicides, etc. These pesticides play an important role in agricultural production and can improve the yield and quality of crops.

(3) Chemical fiber raw material

dimethyl sulfoxide can be used as chemical fiber raw material for the production of polyester, acrylic and other synthetic fibers. These synthetic fibers are widely used in textiles, clothing and other fields.

(4) Petroleum processing aids

Dimethyl sulfoxide can be used as a petroleum processing aid to improve oil recovery and processing efficiency. In addition, dimethyl sulfoxide can also be used for the preparation of lubricating oil, fuel oil and other petroleum products.

In short, dimethyl sulfoxide as an important chemical raw material, its upstream and downstream related products are very extensive, involving medicine, pesticides, chemical fiber, petroleum processing and other fields.
