3-Hydroxybenzoic acid powder Raw Materials CAS 99-06-9
Product Overview:
3-Hydroxybenzoic acid powder white crystal; 3-Hydroxybenzoic acid can be used as fungicides, preservatives, plasticizers and pharmaceutical intermediates, and can also be used for the synthesis of azo dyes. 3-Hydroxybenzoic acid powder is used as an intermediate in the preparation of herbicide fungicide, preservative, ion exchanger, plasticizer and medicine, and can also be used to synthesize azo dyes; The preparation method used to be benzoic acid as raw material, sulfonated with sulfuric acid, further alkali melting, and then acidified to 3-Hydroxybenzoic acid powder. This method has strong corrosion, high temperature and poor operating environment, so it is no longer used. Instead, mecresol is used as raw material to protect the carboxyl group with acetic anhydride or acetyl chloride to become acetate, and then the corresponding carboxyl acid is oxidized by air in the presence of catalyst, and then the finished product is obtained by hydrolysis.
