PROCESS FOR PREPARATION OF HERBICIDAL SALTS.

摘要

A process for the preparation of solid amine salts of aromatic substituted carboxylic acid herbicides by reaction of the aromatic substituted carboxylic acid herbicide with an amine comprising reacting the aromatic substituted carboxylic acid herbicide in an ether solvent with an amine to form the amine salt and collecting the amine salt of the aromatic substituted carboxylic acid herbicide as a precipitate from the ether solvent reaction mixture wherein the ether is a dialiphatic ether comprising at least one primary aliphatic group.
