Catalytic reaction device for preparing 2, 4-dibromopyridine

Abstract

The invention discloses a catalytic reaction device for preparing 2, 4-dibromopyridine. The catalytic reaction device comprises a supporting seat, a reaction kettle main body, a supporting plate, a heating pipe, a fixing mechanism, a damping mechanism and a dismounting mechanism; the fixing mechanism is located at one side of the supporting plate; the fixing mechanism comprises a first fixing plate and a second fixing plate. According to the catalytic reaction device of the invention, the first fixing plate and the second fixing plate are arranged, so that inconvenience in fixing heating pipeswith different specifications and sizes is effectively prevented, the heating effect of the device is ensured, and therefore, the universality of the device is greatly improved; rubber columns are adopted, so that vibration caused by the fact that a motor on the device cannot be buffered during working is effectively avoided, the stability of the device is improved, and therefore, the service life of the device is prolonged; an arc-shaped plate is adopted, so that the problem that a stirring rod on the device is inconvenient to disassemble and replace when being damaged due to long-time use is effectively avoided, the stirring effect of the device is guaranteed, and reaction efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of reaction devices, and specifically relates to a catalytic reaction device for preparing 2,4-dibromopyridine. Background technique [0002] As an organic chemical raw material, 2,4-dibromopyridine is mainly used in pharmaceutical intermediates and organic synthesis raw materials. Catalytic reaction devices are needed in the production process. [0003] However, the existing catalytic reaction device still has some defects during use. It is inconvenient to fix the heating tubes of different specifications and sizes during use, and the heating effect of the device cannot be guaranteed, thereby reducing the versatility of the device. The motor on the device is working. Unable to buffer and produce vibration, the stability of the device is poor, thus shortening the service life of the device, and when the stirring rod on the device is damaged after long-term use, it is inconvenient to disassemble and replace, and the...

[0003] However, there are still some defects in the existing catalytic reaction device during use. It is inconvenient to fix heating tubes of different sizes during use, and the heating effect of the device cannot be guaranteed, thereby reducing the versatility of the device. When the motor on the device is working Unable to cache and generate vibration, the stability of the device is poor, thereby shortening the service life of the device, and when the stirring rod on the device is damaged after long-term use, it is inconvenient to disassemble and replace, the stirring effect of the device cannot be guaranteed, and the reaction efficiency is low problem, for which we propose a catalytic reaction device for the preparation of 2,4-dibromopyridine
