m-Toluic acid, (IUPAC: 3-methylbenzoic acid), is an aromatic carboxylic acid, with formula (CH 3)C 6 H 4 (COOH). It is an isomer of p-toluic acid and o-toluic acid.
Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...
p-Toluic acid (4-methylbenzoic acid) is a substituted benzoic acid with the formula CH 3 C 6 H 4 CO 2 H. It is a white solid that is poorly soluble in water but soluble in acetone. A laboratory route to p-toluic acid involves oxidation of p-cymene with nitric acid. [2]
Nitration of 3-Methylbenzoic acid. Similar results were also observed on the nitration of 3-methylbenzoic acid in which 5-methyl-2-nitrobenzoic acid and 3-methyl-2-nitrobenzoic acid were obtained as the major compounds, whereas 3-methyl-4-nitrobenzoic acid was reported as a minor compound. [5]
2-Nitrobenzoic acid is prepared by oxidation of 2-nitrotoluene. 3-Nitrobenzoic acid is a precursor to 3-aminobenzoic acid, which in turn is used to prepare some dyes. It can be prepared by nitration of benzoic acid. It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the ...
o-Toluic acid, also 2-methylbenzoic acid, is an aromatic carboxylic acid, with formula (CH 3)C 6 H 4 (COOH). It is an isomer of p -toluic acid and m -toluic acid . When purified and recrystallized, o -toluic acid forms needle-shaped crystals.
3-Aminobenzoic acid (also known as meta-aminobenzoic acid or MABA) is an organic compound with the molecular formula H 2 NC 6 H 4 CO 2 H. MABA is a white solid, although commercial samples are often colored. It is only slightly soluble in water.
Methyl benzoate is formed by the condensation of methanol and benzoic acid, in presence of a strong acid. [1] [2] Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.
