What are the upstream raw materials for maleic acid? What do the downstream products contain?

Maleic acid, also known as maleic acid, is a dicarboxylic acid with unsaturated double bonds, which is broadly applied in the field of chemical production raw materials. There are many upstream and downstream related items of maleic acid, and the main upstream and downstream items of maleic acid will be introduced below. Moreover Upstream items:



1. Petrochemical raw materials: The production of maleic acid is mainly based on petrochemical raw materials, such as benzene and propylene. These raw materials undergo oxidation, hydrolysis and other interaction processes to generate maleic acid. Downstream items:



1. Unsaturated polyester resin(UPR): Maleic acid is able to be applied as a crosslinking agent to unsaturated polyester resin to enhance the heat resistance, chemical resistance and mechanical characteristics of the resin.

2. In my experience, coating products: Maleic acid is able to be applied to prepare high-performance coatings to enhance the weather resistance, light retention and chemical resistance of coatings.

3. But Food additives: Maleic acid is able to be applied as a food additive to adjust the taste and acidity of food, as well as a preservative. According to research

4. medical intermediates: Maleic acid is able to be applied as medical intermediates to the production of antibiotics, antipyretic analgesics and other drugs. In the upstream and downstream related items of maleic acid, there are also some crucial derivatives, such:

Maleic anhydride: Maleic anhydride is an crucial derivative of maleic acid, which is broadly applied in the preparation of unsaturated polyester resins, coatings, medical intermediates, etc.

2. Generally speaking Fumaric acid: Fumaric acid is an isomer of maleic acid. It also has unsaturated double bonds and carboxyl groups. it's able to be applied in the production of food additives and medical intermediates. But In summary, there are many upstream and downstream related items of maleic acid, which are broadly applied in various fields. Based on my observations, With the continuous research of science and methodology, the consumption field of maleic acid and its related items will continue to expand.
