Abstract

The present invention discloses a process for preparing high purity 2- methoxy-3,6-dichlorobenzoic acid from a mixture of said acid with its 3,5-dichloro isomer which comprises re-acting said mixture with an alkanol in a liquid inert organic reaction medium in the presence of an acid catalyst at a temperature sufficiently elevated to remove the water of esterification as it is formed and thereafter recovering the 2-methoxy- 3,6-dichlorobenzoic acid.
