As an important raw material for chemical production, dibasic ester is widely used in various fields. In the upstream and downstream industry chain, divalent esters are associated with many products. This article will detail the upstream and downstream related products of divalent esters.

Upstream Associated Products:

1. Ethanol: Ethanol is one of the main raw materials for the production of dibasic esters. Ethanol is esterified with acetic acid in the presence of an acid catalyst to form a divalent acid ester. Therefore, the yield and price of ethanol have a great influence on the production of the dibasic ester.
2. Acetic acid: Acetic acid is another important raw material for the production of divalent acid esters. The supply and price of acetic acid will also affect the production cost of the dibasic ester.

Downstream Related Products:

1. Plastics: Divalent acid esters can be used to produce various plastic products, such as polyester fibers, films, containers, etc. Therefore, the demand for plastic products will affect the consumption of dibasic esters.
2. Coatings: Divalent acid esters can be used as solvents and film-forming substances for the production of various coatings. Changes in demand in the coatings market will affect the consumption trend of dibasic esters.
3. Adhesives: Divalent esters can be used to produce adhesives, which are widely used in wood processing, packaging, construction and other industries. Demand changes in the adhesive market will affect the consumption of dibasic esters.
4. Food additives: Divalent acid esters can be used as food additives to improve the taste and quality of food. Therefore, the demand of the food additive market will also have a certain impact on the consumption of dibasic esters.

In summary, the upstream and downstream related products of divalent esters are extensive and involve many fields. With the change of market demand and the continuous progress of technology, the upstream and downstream industrial chain of dibasic ester will continue to develop and improve.
