Reaction Steps
In a process for the synthesis of terephthalic acid, comprising the oxidation of para-xylene in acetic acid solution, at a temperature of from 100° to 230° C. and at a pressure from 1 to 30 kg/cm2, and in the presence of a catalytic system based on manganese, bromine and cobalt, whereby water is formed and methyl-acetate is by-produced during the oxidation, whereby solid terephthalic acid is separated from the mother liquor and whereby one withdraws from the oxidation zone a liquid which is obtained by condensing the vapors released during the oxidation and which are mainly consisting of acetic acid and water, the improvement for the recovery of the acetic acid solvent, the catalyst and the methyl acetate, comprising:
