Procatechuic acid, alias: 3,4-dihydroxybenzoic acid, molecular formula: (HO) 2C6H3COOH, white to brown crystalline powder, discoloration in air. Density: 1.54g/cm3, melting point: about 200 °C (decomposition); soluble in ethanol, ether.
Protocatechuic acid is mainly used in the fields of medicine synthesis, organic intermediates synthesis, dye synthesis and chemical reagents. It is also the core raw material of a variety of pharmaceutical products (e.g. anti-cancer drug Erotinib, sodium channel inactivation gate inhibitor veratridine, respiratory drug Maipifanlin hydrochloride, treatment of hepatitis B drug Huberine II, new drug). Itopride hydrochloride, a gastrointestinal motility drug, and Yimixing, an anesthetic. In addition, protocatechuic acid itself also has antimicrobial effect, but also has expectorant, antiasthmatic effect, clinical use in the treatment of chronic tracheitis.
In recent years, with the application of protocatechuic acid in medicine, feed, environmental protection and other fields, the output and demand of protocatechuic acid have increased steadily, with an average annual growth rate of about 10%. In 2015, the global total output is about 250 tons, which has great market development space. At present, the domestic production enterprises of protocatechuic acid basically adopt chemical process, but the three wastes of chemical synthesis are large, which is in contradiction with the current environmental protection policy of our country. The pressure of environmental protection of production enterprises is generally high. Some production enterprises have stopped production and rectified. Therefore, the development of green environmental protection production technology has greater competitiveness. The direction of industrial development.
After years of technological optimization and equipment adjustment, Nanjing Shunxiang Factory has been able to provide high-quality protocatechuic acid with purity of more than 98%. The equipment and facilities used in the production of Nanjing Shunxiang meet the requirements of environmental protection, and can provide the best safe storage and transportation conditions.
