Abstract

Кислород или обогащенный кислородом газ используют при получении терефталевой кислоты в реакционной системе, которая позволяет уменьшить связанную с этим пожароопасность. Достигаются уменьшенный расход реагента и растворителя в сочетании с образованием уменьшенных количеств нежелательных побочных продуктов, уменьшенными расходами, связанными с отработкой отходящих газов, и уменьшенным воздействием на окружающую среду в сравнении с тем, что имеет место в ходе обычного процесса получения терефталевой кислоты на основе воздуха.
