  The present invention generally relates to processes for purification, recovery, and conversion of chlorophenol salts (e.g., 2,5-dichlorophenol and salts thereof). In various aspects, the present invention is related to removing one or more impurities from chlorophenol salt-containing process streams and/or recovering chlorophenol salts from process streams for use of the recovered chlorophenol elsewhere in an integrated process. Process streams that may be treated in accordance with the present invention include those incorporating one or more chlorophenol salts in a feed mixture and also those where one or more chlorophenol salts are present in a product or by-product stream of an integrated process. For example, conversion processes of the present invention are suitable as one piece of an integrated process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or a salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or a salt or ester thereof. The present invention further relates to processes for preparation, purification, and recovery of intermediates formed in integrated processes utilizing chlorophenol salts such as 2,5-dichlorophenol as starting material, including the intermediate 3,6-dichlorosalicylic acid (3,6-DCSA) formed during preparation of dicamba from 2,5-dichlorophenol.

  本发明一般涉及氯酚盐（如2,5-二氯苯酚及其盐类）的提纯、回收和转化工艺。在各个方面，本发明涉及从含氯酚盐的工艺流中去除一种或多种杂质，和/或从工艺流中回收氯酚盐，以便在集成工艺的其他地方使用回收的氯酚。可根据本发明处理的工艺流包括在进料混合物中含有一种或多种氯酚盐的工艺流，以及在综合工艺的产品或副产品流中含有一种或多种氯酚盐的工艺流。例如，本发明的转化工艺适合作为生产 3,6-二氯-2-甲氧基苯甲酸（麦草畏）或其盐或酯的综合工艺或生产 2,4-二氯苯氧乙酸（2,4-D）或其盐或酯的工艺的一部分。本发明还涉及利用氯酚盐（如 2,5-二氯苯酚）作为起始原料的综合工艺中形成的中间体的制备、纯化和回收工艺，包括从 2,5-二氯苯酚制备麦草畏过程中形成的中间体 3,6-二氯水杨酸（3,6-DCSA）。

  Fifty-four polychlorinated diphenyl ether (PCDEs) congeners were synthesized, and their structures were confirmed by mass spectrometry and proton magnetic resonance spectroscopy. The gas chromatographic relative retention times (RRT) for the PCDEs were determined relative to a reference standard, [C-13-3,3',4,4']-tetrachlorobiphenyl (PCB 77) on the fused silica capillary columns of SE-54 and OV-1701. The retention times for PCDEs increased with the increasing number of vicinal chlorines within a series of isomers. The chlorine substitution patterns of PCDEs were used to develop a method for predicting RRTs for congeners that were not synthesized.
