[Chemical Knowledge]:What are the upstream raw materials for dibasic acid diols? What do the downstream products contain?

Dibasic acid diol has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following are some common upstream and downstream related products of dibasic acid diols:

1. Upstream and downstream related products: dibasic acid ester
dibasic acid and diol can be esterified to produce dibasic acid ester. Common dibasic acid esters include diethyl phthalate, dioctyl adipate, etc., which are widely used in plastics, rubber, fibers and other fields.
2. Downstream associated products: polyurethane
diols can react with diisocyanates to generate polyurethane. Polyurethane has excellent elasticity, wear resistance, chemical resistance, etc., and is widely used in furniture, construction, automobiles, shoes and other fields.
3. Downstream related products: Epoxy resin
diols can react with epoxy resin to generate alkyd resin. Alkyd resin has good weather resistance, light retention, construction and other advantages, commonly used in coatings, inks and other fields.
4. Downstream Associated Products: Polyester
dibasic acids and diols can undergo polycondensation reactions to produce polyester. Polyester has the advantages of high strength, high modulus and heat resistance, and is widely used in fiber, film, container and other fields.

In short, the upstream and downstream related products of dibasic acid diols are very extensive, involving plastics, rubber, fibers, coatings, inks and other fields.
