V made from gallnut. The main component of gallnut tannic acid, is a hydrolysis tannin, soluble in hot water, with astringent taste, and species of amorphous complex organic matter. Chinese gallnut tannin is a complex mixture of gallic acid, dicalcium and glucose in the form of glycosides or esters. Tannin is hydrolyzed to produce gallic acid and glucose. Hydrolyzed into gallate, and then gallic acid hydrolysis into gallic acid, hydrolysis temperature of 133-135 ° C, the pressure of 0.18-0.2MPa. From the pressure rise to 0.18MPa start the reaction to maintain 2h to reach the end point. Compared with atmospheric hydrolysis, sulfuric acid and steam can be saved, the production capacity can be increased by 25%.
With antibacterial effect, can treat bacillary dysentery. With convergence, bleeding, anti-diarrhea effect. Can be used as a preservative. Coke can be prepared from gallic acid, drugs, ink, media dyes and explosion-proof agent. Also used as a developer and detection of free inorganic acids, dihydroxy acetone, alkaloids and metals and other analytical reagents.
