GENERAL DESCRIPTION AND APPLICATIONS |
||
Gallic Acid, chemically 3,4,5-trihydroxybenzoic acid, C6H2(OH)3COOH, is A clear crystalline compound found in many plantsn but can be prepared commercially by the hydrolysis of tannic acid with sulfuric acid. Gallic acid has two fuctional groups in the same molecule, hydroxyl groups and a carboxylic acid group. They can yield various kinds of esters and salts. Gallic acid forms pyrogallol, or 1,2,3-trihydroxybenzene, C6H3(OH)3, which are widely used in the manufacturing azo dyes and photographic developers and to treat certain skin diseases. Gallic acid and its derivatives are used in making dyes and inks, photographic developers and used as astringents in medically. Some gallates are used as antioxidants in foods. Tannins (tannic acid or gallotannic acid) are are esters of digallic acid. They are widely used in tanning leather , dyeing fabrics, manufacturing inks, and in various medical applications (as astringents and to treat some skin diseases). | ||
