High-pressure kettle equipment for high-pressure kettle method synthesis based on mesalazine and preparation process

Abstract

The invention provides high-pressure kettle equipment for high-pressure kettle method synthesis based on mesalazine and a preparation process, and relates to the technical field of high-pressure kettle equipment, the high-pressure kettle equipment comprises a water tank and a sliding block; the water tank is of a rectangular block structure with the hollow interior, and a control panel is arranged on the front side of the water tank. The sliding block is of a rectangular block structure, and a penetrating type screw hole structure is formed in the front side of the top of the sliding block. The sliding block further comprises a kettle cover, the kettle cover is fixedly arranged on the front side of the sliding block, and the kettle cover is of a circular plate-shaped structure; a control ring is rotationally arranged at the top of the kettle cover; the six sets of nuts are arranged, and tooth groove structures are formed in the outer sides of the nuts, so that the phenomenon that the kettle cover inclines due to uneven stress is avoided, the sealing effect is improved, meanwhile, the mounting and dismounting efficiency of the kettle cover is greatly improved, and the problems that in an existing mode, the closing efficiency is low, and the sealing effect is poor are solved. And the possibility that the kettle cover is inclined still exists.

Description

technical field [0001] The invention relates to the technical field of autoclave equipment, in particular to autoclave equipment and a preparation process for synthesis based on the mesalazine autoclave method. Background technique [0002] Autoclave equipment is an industrial equipment for chemical reactions under high pressure, and some are equipped with stirring or heat transfer devices. In the production of mesalazine drugs, an autoclave is usually required. [0003] However, the current autoclave still has the following shortcomings: [0004] In the process of closing the autoclave cover of the existing autoclave, it is usually necessary to tighten two sets of symmetrical nuts at a time, so as to avoid the phenomenon that the autoclave cover is tilted due to uneven force and affects the connection between the autoclave cover and the autoclave body. However, the existing method is not only slow in closing efficiency, but also has the possibility of causing the lid of th...

AI Technical Summary

Problems solved by technology

[0004] In the process of closing the lid of the existing autoclave, it is usually necessary to tighten two sets of symmetrical nuts at one time, so as to avoid the tilting of the lid due to uneven stress and affect the connection between the lid and the body. Sealing, but the existing method not only has a slow closing efficiency, but also has the possibility of causing the kettle cover to tilt, which is not conducive to the operation and use of the equipment
