Chemical properties
It appears as white needle crystal. It will contain crystal water upon crystallization from the water. It appears as an anhydride at 100 ℃. Melting point 218-219 ° C (it has a melting point of 213 ° C upon thermal shock). Soluble in hot water, ethanol, ether. Cooking in water, acid or salt solution will remove carbon dioxide. It exhibits red color upon reaction with ferric chloride.
Application
- The product has the chemical properties of both resorcinol and salicylic acid. It can be used in chemical reagents for colorimetric determination of iron, titanium and other elements; for organic synthesis, it is mainly used for dyes and pharmaceutical intermediates. 2, 4-dihydroxybenzoic acid is a major raw material during the production of acidic medicated pink 3BM, which consumes 157 kg per ton of dye (by 100%).
- Used as a dye intermediate, medicine and reagents
- Used as dyes, pharmaceuticals, pesticide intermediates
Preparation
It is derived from the hydroxylation of resorcinol.
Chemical Properties
Dihydroxybenzoic acid is a colorless solid and is used as a flavor modifier.
Chemical Properties
cream to slightly beige or pink crystalline powder
Occurrence
Reported present in avocados, beer, red wine, roast coffee, sherry, smoked sausage and white wine
Uses
2,4-Dihydroxybenzoic acid is used in Intermediates, Plasticizers, Plastic and Rubber Products, a organic building block.
Uses
Intermediate for dyestuffs and drugs; spot test reagent for iron.
Preparation
Prepared from resorcinol and potassium bicarbonate in glycerol or water by heating and passing carbon dioxide through the mixture.
Purification Methods
Crystallise the acid from water. [Beilstein 10 IV 1420.]
