Problems exist in the production process of p-chlorobenzaldehyde
Thread Content
In the production process of p-chlorobenzaldehyde, there is a problem with the difficulty in separating p-chloro-1-chlorobenzene and p-chloro-2-chlorobenzene. Can experts solve this issue? New separation technologies are available as alternatives. The normal pressure boiling point of p-chlorobenzyl chloride is 221 degrees, that of p-dichlorobenzyl chloride is 234 degrees, and that of p-trichlorobenzyl chloride is 245 degrees.
