The atmospheric boiling point of acetic acid is about 180° F. and water and solid solutes tend to increase the boiling point. Evaporative crystallization involves the distillation of the solvent to promote crystallization of the solute. By distilling acetic acid from the single stage crystallization zone, acetic acid solvent can be recovered.

The meta form is isophthalic acid (1,3-benzenecarboxylic acid). It is a white crystals sub at 345°C slightly soluble in water, alcohol and acetic acid (insoluble in benzene). It is obtained by oxidizing meta-xylene with chromic acid, or by fusing potassium meta-sulphobenzoate, or meta-brombenzoate with potassium formate.
Substitution of the meta-phthalic isomer, isophthalic acid, for the ortho PA is the most common commercial route to cooking higher molecular weight unsaturated polyester resins. Resins with (by GPC) number average molecular weights of 1,500 to 2,000 can be easily made.

Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(COOH)2. Phthalic acid is used mainly in the form of the anhydride to produce other chemicals such as dyes, perfumes, saccharin, phthalates and many other useful products. Phthalic acid, when found in tissues or biofluids arises from exposure to these phthalate products.
Phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2. It is an isomer of isophthalic acid and terephthalic acid. Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale.
