Claims (1)

Раскрывается способ получения ароматической карбоновой кислоты, который включает окисление в жидкой фазе исходного ароматического соединения, содержащего по меньшей мере одну способную к окислению алкильную или ацильную группу кислород-содержащим газом в растворителе, содержащем низкомолекулярную карбоновую кислоту в присутствии катализатора окисления, содержащего компоненты тяжелых металлов с образованием реакционной смеси продуктов окисления, содержащем ароматическую карбоновую кислоту, последующее нагревание реакционной смеси продуктов окисления при температуре по меньшей мере приблизительно при 550°F с получением второй смеси продуктов реакции, выделение из второй смеси продуктов ароматической карбоновой кислоты. Предлагаемый способ обеспечивает получение более чистой ароматической карбоновой кислоты, имеющей больший размер частиц.A method for producing an aromatic carboxylic acid is disclosed, which involves oxidation in the liquid phase of a starting aromatic compound containing at least one oxidizable alkyl or acyl group with an oxygen-containing gas in a solvent containing low molecular weight carboxylic acid in the presence of an oxidation catalyst containing heavy metal components with the formation of the reaction mixture of oxidation products containing an aromatic carboxylic acid, the subsequent heating of the reaction see si oxidation product at a temperature of at least about 550 ° F to obtain a second reaction product mixture, separation of a second mixture of aromatic carboxylic acid product. The proposed method provides a more pure aromatic carboxylic acid having a larger particle size.
