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

In my experience, Fumaric acid has an crucial position in the field of chemical production raw materials, and its upstream and downstream related items are broadly applied. And In my experience, The main upstream and downstream associated items of fumaric acid will be described in detail below. Upstream items:



1. For example Maleic Anhydride(maleic anhydride): Maleic anhydride is the main raw material to the production of fumaric acid. Fumaric acid is able to be obtained by adding aquatic environments to the ring opening interaction. But Additionally Downstream items:



1. And In my experience, According to research Unsaturated polyester resin(Unsaturated Polyester Resin): Fumaric acid is able to be applied as a interaction monomer, and other unsaturated dibasic acids, diols and other raw materials to polycondensation interaction to generate unsaturated polyester resin. This resin has good chemical resistance, heat resistance, electrical insulation and other characteristics, broadly applied in FRP, coatings, adhesives and other fields. In fact

2. Based on my observations, Dimethyl fumarate(Dimethyl Fumarate): Fumaric acid reacts with methanol to generate dimethyl fumarate, which is a frequently applied food preservative that is able to efficiently inhibit the development of molds and bacteria and extend the shelf life of food. Based on my observations,

3. For instance Ferrous fumarate(Ferrous Fumarate): Fumaric acid reacts with iron salt to create ferrous fumarate, which is a frequently applied food nutrition fortifier to supplement the iron required by the people body and prevent iron deficiency anemia.

4. But Ethyl fumarate(Ethyl Fumarate): Fumaric acid reacts with ethanol to create ethyl fumarate, which is a fragrant compound that is able to be applied as a food additive and flavor. In short, the upstream and downstream related items of fumaric acid are extensive, involving many fields, such as coatings, adhesives, food preservation, nutrition fortification and so on. Specifically The production and consumption of these items provide crucial support to the research of chemical, food and other industries.
