TEREPHTHALIC ACID PRODUCTION |
摘要 |
An improved process for the production of terephthalic acid comprising introducing a feed directly into a recirculating liquid stream so as to facilitate formation and maintenance of gas bubbles in a dispersed form in a recirculating gas bubble-liquid mixture. By maintaining a gas-liquid interface and overhead gas phase in conjunction with a quiescent zone of liquid apart from the major portion of liquid in which said mixture is maintained in a recirculating flow condition, the loss of appreciable amounts of gas to the overhead gas phase is avoided. |
