2,4-Dihydroxybenzoic acid Usage And Synthesis
Uses2,4-Dihydroxybenzoic acid is a useful synthetic intermediate. An organic building block for plastics and rubber products.
ToxicityGRAS (FEMA).
Usage limitsFEMA (mg/kg): cold drink: 450; Meat, dairy, processed vegetables, 100; fudge, gel, pudding, snack food, beverages, breakfast cereals, fats, cheeses, poultry products, fish, spices, sweet sauce, dairy products, meat soup, fruit ice Egg products, jams, jelly, rehydrated vegetables, 500; soup: 250; jelly sugar: 3333; instant coffee and tea: 12.5; sugar substitute: 12500; seasoning spices: 25000.
Chemical propertiesIt 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
PreparationIt is derived from the hydroxylation of resorcinol.
Chemical Propertiescream to slightly beige or pink crystalline powder
Chemical PropertiesDihydroxybenzoic acid is a colorless solid and is used as a flavor modifier.
OccurrenceReported present in avocados, beer, red wine, roast coffee, sherry, smoked sausage and white wine
Uses2,4-Dihydroxybenzoic acid is used in Intermediates, Plasticizers, Plastic and Rubber Products, a organic building block.
UsesIntermediate for dyestuffs and drugs; spot test reagent for iron.
PreparationPrepared from resorcinol and potassium bicarbonate in glycerol or water by heating and passing carbon dioxide through the mixture.
Purification MethodsCrystallise the acid from water. [Beilstein 10 IV 1420.]
