| titleOfInvention | Method and device for manufacturing ethyl cyclo hexand by catalytic hydration in the liquid phase |
| abstract | The invention relates to a process for the preparation of ethylcyclohexane by hydrogenation of ethylcyclohexane contaminated with ethylbenzene or 4-vinylcyclohexene on a suspended in the liquid phase noble metal catalyst and a device suitable for carrying out the method.n n n Based on the disadvantages of the known prior art, a method is to be created that is suitable for large-scale implementation and can be produced inexpensively with the ECH in high purity.n n n For this purpose, it is proposed as a solution that the reaction is carried out in a plurality of reaction cycles in a loop reactor, wherein a) in a start-up phase as starting material a first subset of ECH presented, catalyst added, rendered inert and the inerting agent is replaced by hydrogen, the reaction mixture circulated in the circuit, the reactor heated to reaction temperature and the startup phase is terminated when the hydrogen uptake to a predetermined limit has sunk; b) at the beginning of the subsequent first reaction cycle, the reactor with the second portion of starting material, either technical ethylcyclohexane or 4-vinylcyclohexene, is filled, the reactor contents are pumped and the reaction cycle is terminated when the hydrogen absorption has dropped to the predetermined limit, immediately after Termination of this reaction cycle is removed from a predetermined subset of hydrogenation product; c) during all further reaction cycles, the removed after the previous reaction cycle subset of hydrogenation product is replaced by either technical ethylcyclohexane or 4-vinylcyclohexene, pumped around the reactor contents and terminated after reaching the limit for the hydrogen uptake of the respective reaction cycle; and during the individual reaction cycles, a reaction temperature of 60 to 130 ° C and a pressure of 5 to 20 bar are maintained, hydrogen introduced via a incorporated in the loop reactor dispersing, the reaction mixture is fluidized and monitored the reactivity of the catalyst and with greatly decreasing reactivity of the Catalyst the reaction is terminated. |
