Let’s keep talking about the application of 2-Furoic acid: 2 5-Furandicarboxylic acid was prepared from 2-Furoic acid.
2-Furoic acid is also known as 2-furanic acid, pyroviscoic acid.
Colorless crystal. Melting point 133 ~ 134℃. Boiling point 230 ~ 232℃. Slightly soluble in cold water, soluble in hot water, ethanol and ether. It is made from furfural by oxidation. Used as a preservative, fungicide, also used in the manufacture of spices, etc.
Hot Application of 2-Furoic acid CAS 88-14-2: 2 5-Furandicarboxylic acid was prepared from 2-Furoic acid.
2, 5-Furandicarboxylic acid can be directly used in the preparation of high performance engineering plastics such as polyester, epoxy resin, polyamide and polyurethane, because of its rigid furan ring and opposite diformic acid group structure. The polymer prepared with 2, 5-Furandicarboxylic acid has excellent mechanical properties in terms of strength, modulus and creep resistance, as well as higher glass transition temperature and thermal deformation temperature. In addition, 2, 5-Furandicarboxylic acid itself can also be used as chemical raw materials and pharmaceutical intermediates.
At present, the main synthesis method of 2, 5-Furandicarboxylic acid is 5-hydroxymethyl furfural (HMF), which is expensive. The method has the disadvantages of low total yield and high cost, and it is difficult to achieve large-scale industrial application. Using 2-Furoic acid as raw material, 2-acyl-5-furanediformic acid was obtained by acylation reaction, and then 2 5-Furandicarboxylic acid was prepared with high yield.
A new path for the preparation of 2, 5-Furandicarboxylic acid was developed. High purity 2 5-Furandicarboxylic acid was prepared with 2-furoic acid as raw material, thus opening up a technical route to synthesize high performance engineering materials from 2-furoic acid. The raw material 2-furoic acid can be derived from biomass resources, so this method can drive the bio-based polymer material industry to gradually get rid of the dependence on petroleum resources, and promote the sustainable development of the whole polymer material industry.
