Procedure to isolate acid, 3 - 2-chloro-4 - (trifluoromethyl) phenoxy - benzoic acid from an aqueous solution of metal Salt

摘要

3 - [2-Chloro-4 - (trifluoromethyl) - phenyl] - benzoic acid a process for separation from an aqueous solution of a metal salt thereof, and conversion from a metal salt of 3 - [2-Chloro-4 - (trifluoromethyl) - phenyl] acid to benzoic acid containing organic or inorganic acids; (b) The larva mixture is heated until a liquid biphasic system composed of organic phase and water phase is formed; (c) the organic phase and water phase are separated.
