摘要： An improved production method of aromatic carboxylic acid products of significantly improved yield and quality by oxidizing alkyl aromatic substrates or their partially oxidized intermediates in a conventional MC-type catalyst system modified to contain additional components such as alkali metal or alkaline earth metal in an acetic acid medium in a feed gas containing oxygen and optionally carbon dioxide. Since carbon dioxide functioned as a co-oxidant along with oxygen in the oxidation reaction, the oxidation reaction proceeds more selectively to produce the carboxylic acid product much faster under milder reaction conditions over the conventional MC-type oxidation. In particular, the oxidation of para-xylene carried out by the novel present method enabled production of terephthalic acid of higher yield and enhanced quality, which were improved far more than the extent that generally could be expected by current PTA producers. The present invention also provides an effective purification process to produce highly pure terephthalic acid or isophthalic acid by the oxidation of impurities such as 4-carboxybenzaldehyde and para-toluic acid or 3-carboxybenzaldehyde and meta-toluic acid contaminated in crude terephthalic acid and isophthalic acid product, respectively.
摘要翻译： 通过在常规的MC型催化剂体系中氧化烷基芳香族基质或其部分氧化的中间体，在醋酸中含有另外的成分如碱金属或碱土金属，改进了产率和质量的改善的芳族羧酸产物的生产方法 在含有氧气和任选的二氧化碳的进料气体中的介质。 由于二氧化碳在氧化反应中作为辅助氧化剂与氧气一起起作用，因此与常规的MC型氧化相比，在较温和的反应条件下，氧化反应更有选择性地进行得更快地产生羧酸产物。 特别地，通过新颖的本发明方法进行的对二甲苯的氧化使得能够生产更高产率和更高质量的对苯二甲酸，其得到的改善远远超过现有PTA生产者普遍预期的程度。 本发明还提供了一种有效的纯化方法，通过氧化杂质如4-羧基苯甲醛和对甲苯甲酸或3-羧基苯甲醛和在对苯二甲酸和间苯二甲酸中污染的间甲苯甲酸，产生高纯对苯二甲酸或间苯二甲酸 产品。

摘要： The present invention relates to a method for preparing high-purity terephthalaldehyde which comprises re-crystallizing terephthalaldehyde crystals containing impurities, using an anti-solvent. Specifically, the present invention relates to a method for preparing terephthalaldehyde which comprises dissolving low-purity terephthalaldehyde prepared by a conventional method in dimethylsulfoxide and then re-crystallizing the solution, using water as an anti-solvent. The present invention is not only environment-friendly because it uses water only as an anti-solvent, but also economical because it may simply prepare high-purity terephthalaldehyde in a short time.
