摘要:
Various processes for the separation of a mixture containing dichlorophenols are described. In various aspects, the present invention relates to separation processes that produce an extract enriched in 2,4-dichlorophenol content and an extract enriched in 2,5-dichlorophenol content. The present invention further relates to various processes that integrate with these separation processes, such as a process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or salt or ester thereof.
