Main applications of gallic acid

Gallic acid ester compounds can be synthesized from gallic acid. Alkyl esters of gallic acid can be divided into lower esters (such as methyl ester, ethyl ester, propyl ester, etc.) and higher esters (such as octyl ester, lauryl ester, octadecanol ester, etc.) according to the number of alkyl carbon atoms.

Gallic acid preparation method

Acid hydrolysis is mainly divided into one-step method and two-step method. The main process of preparing gallic acid by the two-step method is as follows: raw material → hot water extraction → filtration of filter residue → concentration of tannin aqueous solution to about 20% → acid hydrolysis → cooling crystallization → centrifugation to obtain crude product → dissolution of crude product and carbon decolorization → cooling crystallization after filtration → centrifugation → drying → gallic acid finished product.
