Embodiment

[0025] When the device is installed, several reactors are arranged side by side, such as Figure 7 Said, the discharge pipe on one of the reaction kettles is connected to the feed pipe on another adjacent reaction kettle through the first connecting pipe, and a water pump is set on the first connecting pipe to improve the delivery efficiency of the raw materials, Connect the exhaust pipe on one of the reactors to the inlet pipe on the other adjacent reactor through the second connecting pipe, and so on, connect several reactors in series for the continuous reaction of m-cresol alkylation , increasing its reaction rate. When the power supply of the motor is turned on during use, the output shaft of the motor drives the first rotating shaft connected to it to rotate synchronously. When the first rotating shaft rotates, the corresponding second rotating shaft is driven by the fixed block to rotate with the first rotating shaft as the axis. Under the mutual cooperation of the fir...

Abstract

The invention provides a continuous reaction device for alkylation of m-cresol and p-cresol, and mainly relates to the technical field of reaction kettles. The continuous reaction device for alkylation of m-cresol and p-cresol comprises a reaction kettle, a first rotating shaft is mounted in a first through hole through a bearing, a plurality of obliquely-arranged blades are fixedly mounted on the periphery of a second rotating shaft, a pressure relief mechanism is arranged on one side of the top face of a sealing plate, and a circular ring is mounted on the bottom face of the sealing plate through a bearing. The two sides of the bottom face of the circular ring are hinged to one ends of first inclined rods correspondingly, the other ends of the first inclined rods are hinged to one ends of second inclined rods correspondingly, the other ends of the second inclined rods are hinged to the periphery of the first rotating shaft correspondingly, and the output end of the motor is fixedly connected with the lower end of the first rotating shaft. The reaction device has the beneficial effects that when the reaction device is used, the first rotating shaft rotates to drive the second rotating shaft, the blades, the first inclined rods and the second inclined rods to stir materials in the reaction kettle in different directions, so that the mixing efficiency of the materials is improved.

Description

technical field [0001] The invention mainly relates to the technical field of reactors, in particular to a continuous reaction device for m-cresol alkylation. Background technique [0002] Alkylation is the process of transferring an alkyl group from one molecule to another. It is a reaction process in which an alkyl group is introduced into an organic molecule by addition or displacement reaction. Since the boiling points of m-cresol and p-cresol are very close, it is difficult to separate them directly by rectification, and they usually exist in the form of m-cresol and p-cresol. It is necessary to increase the boiling point of the two through an alkylation reaction before rectification. separation, the existing m-cresol and p-cresol alkylation continuous reaction devices usually use several alkylation reactors connected in series for continuous reaction. When using, the raw materials need to be passed into the reactor for mixing and stirring, and isobutylene The gas is ...
