Abstract
Description
[0002]本発明は、概して芳香族カルボン酸の製造方法に関し、特に精製するための粗芳香族カルボン酸の製造方法に関する。
[0010]本発明の一形態によれば、精製芳香族カルボン酸の製造方法が提供される。粗芳香族カルボン酸および水を含む精製反応混合物を、予熱区域内において予熱する。精製反応混合物は、周囲圧力より高い圧力で予熱区域に導入する。次に、精製反応混合物中の粗芳香族カルボン酸を精製して、精製芳香族カルボン酸生成物を形成する。
[0018]幾つかの態様においては、本方法は、置換芳香族炭化水素を、モノカルボン酸溶媒、水、および触媒組成物を含む液相酸化反応混合物中で気体状酸素によって酸化することを更に含む。幾つかの態様においては、精製は、粗芳香族カルボン酸の少なくとも一部を含む水溶液を触媒の存在下において水素と接触させることを含む。
[0021]図1は、本発明の一態様による精製形態の芳香族カルボン酸を製造するためのプロセスフロー図を示す。簡単な導入として、プロセス100は、供給材料を液相酸化するように構成されている酸化反応器110;液相酸化反応混合物から粗固体生成物を形成するように構成されており、結晶化容器152および156を含む結晶化区域;粗固体生成物(および酸化副生成物)を液体から分離するように構成されている固液分離装置190;精製反応溶媒中の粗固体生成物の混合物を調製するように構成されている精製反応混合物メイクアップ容器(make up vessel)200を含む混合区域;精製反応混合物を精製区域中に導入する前に加熱するための熱交換器208を含む予熱区域;粗芳香族カルボン酸を精製するように構成されている精製反応器210を含む精製区域;精製溶液から精製固体生成物を形成するように構成されている容器220を含む結晶化区域;および精製固体生成物を液体から分離するように構成されている固液分離装置230;を含む。図1における複数のプロセスの統合は単に例示を意味し、種々の他の統合および非統合構成を同様に用いることができる。
