Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to a p-chloroaniline catalyst separation filter. Background Art

[0002] Para-chloroaniline catalysts are usually solid. Such catalysts generally exist in the form of solid powder or granules and are used for fixed-bed catalytic reactions or suspended in a reaction system for liquid-phase catalytic reactions. Solid catalysts are widely used in industrial production because they have the advantages of high stability, easy recovery and reuse, and can effectively catalyze the conversion of substrates, improve the yield and selectivity of the reaction, and thus play an important role in organic chemical synthesis.

[0003] There is a problem in the separation process of the p-chloroaniline catalyst. Since the p-chloroaniline catalyst has a certain viscosity, it is easy to stick to the sieve plate and is difficult to remove from the sieve plate directly and conveniently, which will seriously affect the discharging of the p-chloroaniline catalyst.
