Description

Technical Field

[0001] This utility model relates to the field of p-chlorobenzaldehyde production technology, specifically a novel device for separating p-chlorobenzaldehyde and p-chlorobenzoic acid. Background Technology

[0002] In the traditional production process of p-chlorobenzaldehyde, chlorination followed by acid hydrolysis produces p-chlorobenzoic acid. The common method is to remove p-chlorobenzoic acid by washing with water. However, washing also carries away some p-chlorobenzaldehyde. Some researchers oxidize p-chlorobenzaldehyde in water to p-chlorobenzoic acid, then adjust the pH of the aqueous solution to crystallize the p-chlorobenzoic acid for recovery. The wastewater is then treated with alkali. After this treatment, the p-chlorobenzoic acid content in p-chlorobenzaldehyde can be reduced to 0.5%-0.2%. For products with low requirements, p-chlorobenzaldehyde with a p-chlorobenzoic acid content of 0.5% can be used. However, for products with higher purity requirements, p-chlorobenzaldehyde needs to be washed multiple times to achieve 0.2% or below, generating a large amount of wastewater. Recovering p-chlorobenzoic acid from this wastewater is also costly and not worthwhile. Utility Model Content
