Catalyst addition device and addition method for preparation of o-tert-butylcyclohexanol

Abstract

The invention discloses a catalyst adding device for preparing o-tert-butylcyclohexanol, which belongs to the technical field of chemical product preparation and includes a storage bucket, a feeding mechanism, a quantitative mechanism, and a rinsing activation mechanism. The storage bucket is used for loading a solid catalyst. The lower end of the feeding mechanism is arranged inside the storage bucket, and the feeding mechanism is used to extract the solid catalyst in the storage bucket, and the solid catalyst enters the quantitative mechanism from the storage bucket under the action of the feeding mechanism; the described The quantitative mechanism is arranged on the outer surface of the storage bucket. The quantitative mechanism is used to load a quantitative solid catalyst. The quantitative mechanism adds the quantitative solid catalyst to the rinsing activation mechanism. The rinsing activation mechanism is arranged at the lower end of the quantitative mechanism. The first end of the rinsing and activating mechanism is connected to the liquid inlet pipe, and the second end of the rinsing and activating mechanism is connected to the reaction kettle. The invention can automatically transfer the catalyst by setting the feeding mechanism to realize automatic addition.

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
