Title: Process for the production of terephthalic acid
IPC: C07C51/41
Filed: 1955-03-16
Abstract: Terephthalic acid is made by heating in the presence of an organic diluent which is liquid at the reaction temperature either potassium isoor ortho-phthalate, or a mixture thereof, at 350-480 DEG , preferably 420-480 DEG , especially 440 DEG  C., under pressure in a carbon dioxide atmosphere.  Pressures of 70-150 atmos. are quoted. The starting material may be obtained by converting into neutral salts the oxidation products of commercial xylenes, any potassium carbonate present being preferably converted to the sulphate. Advantageously the phthalates are anhydrous.  Sufficient diluent should be present to form a mobile paste.  Specified diluents are diphenyl, phenyl cresyl oxide, dicresyl oxide and diphenyl oxide, the latter being preferred. The use of a catalyst such as an oxide of zinc, iron, thallium or lead, or of an organic salt of lead such as the oxalate, leads to an increased yield, litharge being preferred. 1 to 6 per cent by weight of catalyst based on phthalate may be used. In examples terephthalic acid is obtained in the presence of diphenyl oxide and lead oxalate from (1) potassium ortho-phthalate; (2) potassium isophthalate; and (3) a mixture of potassium salts from acids obtained by oxidizing commercial xylene and in (4) from potassium isophthalate in the presence of diphenyl oxide and lead oxide.  Reference has been directed by the Comptroller to Specifications 747,204 and 762,644.
