Formula and structure of 2-Chlorobenzoic acid:
2-Chloro benzoic acid is a mono chloro benzoic acid and a 2- halo benzoic acid with the chemical formula C7H5ClO2 which has a chloro group in position 2. It is the conjugate acid of 2- chlorobenzoates.
O-Chlorobenzoic Acid Solubility:
Ortho-Chloro benzoic acid is not soluble in water. Due to the heat of this compound, by adding 2 M HCl, and 2M NaOH and mixing it with methyl 3- nitrobenzoate, it becomes soluble in water.
2-Chlorobenzoic Acid Production Process:
Methods for the preparation of chloro benzoic acid include the oxidation of 2-chlorotoluene and the replacement of the amino group in Anthranilic acid with a chlorine atom. In the oxidation of 2-chlorotoluene, potassium permanganate is used. This method is recommended for relatively large quantities.
