Abstract

Окисление р-ксилола для производства терефталевой кислоты осуществляют с использованием чистого или почти чистого кислорода и испарительного охлаждения, в результате чего уменьшается генерирование побочных продуктов и отходов, увеличивается утилизация кислорода и устраняется необходимость применения в реакторе теплообменных поверхностей прямого контактирования. Описывается также установка для производства терефталевой кислоты.
