3,4-dihydroxybenzoic acid is an important pharmaceutical and chemical intermediates, widely used in the field of medicine and chemical engineering, the demand for 3, 4-Dihydroxybenzoic acid is great at home and abroad. In terms of medicine, 3,4-dihydroxybenzoic acid can play a variety of medical functions, such as antibacterial, anti-inflammatory, anti-tumor, anti-oxidation, analgesic, nerve protection, etc., for example, it can play a certain antibacterial role on Pseudomonas aeruginosa, Escherichia coli, typhoid bacillus, dysentery bacillus, alkali producing bacillus, bacillus subtilis and Staphylococcus aureus.
Faced with a large demand for 3,4-dihydroxybenzoic acid, how to achieve mass production? 3, 4-dihydroxy3-methoxy benzoic acid can be obtained from vanillin as raw material under the action of organic solvent and oxidation catalyst, and 3,4-dihydroxybenzoic acid can be obtained by demethylation reagent. This production process is relatively simple, and the 3,4-dihydroxybenzoic acid is relatively high in yield and purity, and the cost is relatively low, which is suitable for industrial production.
