Description:
Tannic acid has its structure still remain unclear, and is generally considered to be the ester formed by the five hydroxyl groups of glucose and gallic acid acyl group. The industrial tannic aicd can be obtained by the extraction of Gallic and further concentration. After further purification, we can obtain pharmaceutical or reagent tannic acid.
Tannic acid is a pale yellow amorphous powder or shiny scaly-like or sponge-like solid. It has no special smell with bitter taste and convergence. It can be gradually darken upon exposure to air and sunlight. It is soluble in cold water and even infinitely soluble in hot water; it is also soluble in methanol, ethanol, acetone and ethyl acetate but insoluble in benzene, ether, chloroform, petroleum ether and carbon disulfide. The aqueous solution of tannic acid exhibits weak acidic and is easily oxidized with oxidation rate being faster in alkaline solution and the color of the solution being deeper. In coming across trivalent iron ions, the solution exhibits blue-black color and can react with gelatin, alkaloids to generate precipitate.
It can also react with metal ions such as lead, aluminum, and zinc to generate poly-nuclear complexes and insoluble salts with special colors. When being heated to 210 ~ 215 ℃, tannic acid can be decomposed into pyrogallic acid and CO2.
