Adding device and adding method of catalyst for preparing o-tert-butyl cyclohexanol

Abstract

The invention discloses an adding device of a catalyst for preparing o-tert-butyl cyclohexanol, and belongs to the technical field of chemical product preparation. The adding device comprises a storage barrel, a feeding mechanism, a quantifying mechanism and a leaching and activating mechanism. The storage barrel is used for loading a solid catalyst. The lower end of the feeding mechanism is arranged in the storage barrel. The feeding mechanism is used for extracting the solid catalyst in the storage barrel, and the solid catalyst enters the quantifying mechanism from the storage barrel under the action of the feeding mechanism. The quantifying mechanism is arranged on the outer side face of the storage barrel and used for loading a certain amount of the solid catalyst and adding the certain amount of solid catalyst into the leaching and activating mechanism. The leaching and activating mechanism is arranged at the lower end of the quantifying mechanism, a first end of the leaching and activating mechanism is connected with a liquid inlet pipe, and a second end of the leaching and activating mechanism is connected with a reaction kettle. By arranging the feeding mechanism, a catalyst can be automatically conveyed, and automatic adding is achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical product preparation, and in particular relates to a catalyst adding device and method for preparing o-tert-butylcyclohexanol. Background technique [0002] When preparing o-tert-butylcyclohexanol, it is necessary to add o-tert-butylphenol and hydrogen into the reactor, and add a certain amount of catalyst to the reactor for the catalytic reaction. The dosage of the catalyst is quantitative in each reaction , and it is easy to affect the rate of material generation during the reaction, and the Raner-Ni catalyst used needs activation treatment before it can be used; because the activation treatment of the Raner-Ni catalyst is not to excite the active components through ordinary calcination methods, but generally Use activator to carry out activation treatment to it, such as the activation method recorded in patent CN103570500A and patent CN103193638A, based on the above reasons, this has just deter...

[0002] When preparing o-tert-butylcyclohexanol, it is necessary to add o-tert-butylphenol and hydrogen into the reactor, and add a certain amount of catalyst to the reactor for the catalytic reaction. The dosage of the catalyst is quantitative in each reaction , and it is easy to affect the rate of material generation during the reaction, and the Raner-Ni catalyst used needs activation treatment before it can be used; because the activation treatment of the Raner-Ni catalyst is not to excite the active components through ordinary calcination methods, but generally Use activator to carry out activation treatment to it, such as the activation method recorded in patent CN103570500A and patent CN103193638A, based on the above reasons, this has just determined that the Raner-Ni catalyst required for the reaction cannot be uniformly activated in advance. method, the catalytic activity of the Raner-Ni catalyst cannot be guaranteed

[0003] Therefore, if the dosage of the added catalyst cannot be well controlled, it will affect the work efficiency during preparation, and it will also affect the cleaning work after the reaction, which is not conducive to efficient production

[0004] In order to make the procedure of adding catalyst simpler and more efficient, the present invention proposes a catalyst adding equipment and method, which can effectively solve the problem of quantitatively adding catalyst
