Abstract: Hydroxamic acids are efficiently isolated from aqueous reaction media in which they are produced as solids by adding to the reaction mixture with agitation, a coalescing amount of a water insoluble organic liquid, such as a light hydrocarbon or halohydrocarbon, which is a non-solvent for the hydroxamic acids. The coalesced particles float to the surface of the medium leaving behind a clear, aqueous phase which can be drained from the reaction vessel to leave the discrete particles of hydroxamic acid. Buoyancy of the particles is assisted by adding hydrogen peroxide to the reaction mixture or by bubbling air therethrough, usually after the coalescence.
