Stepwise execution of exothermic reactions with participation of carbocations |
摘要 |
The invention relates to a method for carrying out reactions with participation of carbocations, whereby the initial most strongly exothermic phase of the reaction is carried out at high temperature (60 to 120° C.) and short residence time (1 to 30 seconds) in a microreactor and the subsequent less exothermic phases are carried out at optionally lower temperatures in two or more residence time units with longer residence times (1 to 30 seconds). |

1. An improved process for the execution of a reaction with participation of carbocations, which comprises:
(a) carrying out a most strongly exothermic initial phase of the reaction in a microreactor at a high temperature of from 60 to 120° C. and a short residence time of 1 to 30 seconds, and then subsequently (b) carrying out less exothermic phases of the reaction in two or more residence time units, wherein the residence time in a first residence time unit is from 1 to 30 minutes and the reaction temperature in the first residence time unit is lower by 5 to 30° C. than the microreactor. |
