摘要
A method is used to remove an unreacted alcohol from an ester product mixture by a gas stripping. The method involves the feeding of the ester product mixture into proximity of an axis of a rotating packed bed, so as to enable the ester product mixture to flow radially to come in contact with a gas which is introduced into the rotating packed bed. The unreacted alcohol and any other volatile component of low molecular weight are thus stripped from the ester product mixture by the gas entrainment, thereby resulting in production of a purified ester product which is collected at the bottom of the rotating packed bed. The unreacted alcohol and the volatile component, which are entrained in the gas, are discharged via an exit located at the top of the rotating packed bed.
