1,2-pentanediol is an important organic chemical raw material, widely used in medicine, pesticides, cosmetics, plastics, coatings and other fields. In the field of raw materials for chemical production, there are many upstream and downstream related products of 1,2-pentanediol, some of which are described in detail below.

upstream products:

1. Acetaldehyde: Acetaldehyde is one of the main raw materials of 1,2-pentanediol. 1,2-pentanediol can be prepared by the reaction of acetaldehyde and formaldehyde.

2. Formaldehyde: Formaldehyde is also one of the important raw materials of 1,2-pentanediol, which can be obtained by reacting with acetaldehyde.

downstream products:

1. Polyester resin: 1,2-pentanediol can react with dibasic acid to generate polyester resin, which is used to make coatings, adhesives, fibers, etc.

2. Polyurethane: 1,2-pentanediol can be used as one of the raw materials of polyurethane, and diisocyanate reaction to obtain polyurethane, widely used in the manufacture of foam, elastomers, coatings, etc.

3. Plasticizer: 1,2-pentanediol can be used to produce plasticizers to improve the processing performance and flexibility of plastics.

4. pharmaceutical intermediates: 1,2-pentanediol can be used to synthesize some pharmaceutical intermediates, and further prepare various drugs.

In short, 1,2-pentanediol is an important organic chemical raw material, and its upstream and downstream related products are very extensive, involving medicine, pesticides, cosmetics, plastics, coatings and other fields.
