Miroslav Matejka Crack 7.00 Full Version.This invention relates to a process for the production of terephthalic acid from maleic anhydride. More particularly it relates to a process for the production of terephthalic acid from maleic anhydride by oxidation of maleic anhydride with molecular oxygen to produce a mixture of terephthalic acid and its oxidation products and by-product decarboxylation of terephthalic acid. Terephthalic acid and its esters have heretofore been produced commercially by the liquid phase oxidation of paraxylene with molecular oxygen. The liquid phase oxidation of paraxylene with molecular oxygen yields crude terephthalic acid containing small amounts of impurities, primarily paraxylene, and water. The crude terephthalic acid is purified, for example, by one or more of the following procedures: (a) neutralization of the crude terephthalic acid with a mineral acid such as hydrochloric acid; (b) precipitation of the crude terephthalic acid with a suitable organic solvent, e.g., methylene chloride; (c) crystallization of the crude terephthalic acid; and (d) washing the solid terephthalic acid with water. Other purification procedures are also known. Typically, the purified crude terephthalic acid is further processed to form purified terephthalic acid. Purified terephthalic acid is used to produce, among other things, polyethylene terephthalate which is widely used in the manufacture of bottles and packaging materials. The production of terephthalic acid from maleic anhydride by liquid phase oxidation of maleic anhydride with molecular oxygen is known. The oxidation of maleic anhydride using molecular oxygen in the liquid phase to produce terephthalic acid and other products has been described in numerous patents and publications. For example, U.S. Pat. No. 2,833,816 describes the oxidation of ethylenically unsaturated dicarboxylic acids and anhydrides thereof to the
