4-Methyl-3-nitrobenzoic acid Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Uses

General Description

Prismatic crystals or off-white powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

4-Methyl-3-nitrobenzoic acid is a nitrated carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry.

Fire Hazard

Information concerning the flash point of 4-Methyl-3-nitrobenzoic acid is not available. 4-Methyl-3-nitrobenzoic acid is probably combustible.

Purification Methods

Recrystallise the acid from EtOH. The S-benzylisothiuronium salt has m 167168o (EtOH). The acid chloride [10397-30-5] has m 20-21o, b 185o/36mm, and the methyl ester [7356-11-8] crystallises as pale yellow needles from MeOH with m 51o. [Beilstein 9 H 502, 9 II 334, 9 III 2359.]
