Abstract
The present invention relates to a method for depleting halide ions from liquid ammonia, wherein the liquid ammonia is brought into contact with a strongly basic ion exchanger, where the basic structure of the strongly basic ion exchanger is a covalently crosslinked polymer matrix. Furthermore, the present invention relates to the use of an ammonia obtainable according to the invention as starting material in the production of amines.
