| 摘要 |
The present invention relates to a reactor comprising a plurality of reaction zones, a first reaction zone being configured to provide a first residence time for a reaction mixture passing therethrough at a particular flow rate, and a second reaction zone connected in series with the first reaction zone and configured to provide a second residence time for the reaction mixture passing therethrough at the particular flow rate, wherein the second residence time is at least about 1.5 times greater than the first residence time, the reactor further comprising means for bypassing at least one of the first and second reaction zones to reduce the effective residence time of the reaction mixture passing through the reactor.
