Abstract
Certain organotin halides can be recovered in substantially quantitative yield from aqueous media containing an ammonia or amine complex of these halides by adding (1) a non-reactive highly soluble inorganic salt to partially or completely saturate the solution and (2) an amount of a suitable mineral acid sufficient to decompose said complex and then heating the resultant solution as required to effect a separation of the resultant organotin halide from the aqueous phase.
