The present invention removes an acid in the presence of an auxiliary base to remove aminohalophosphine, diaminohalophosphine, triaminohalophosphine, phosphite ester diamide, aminophosphine, diaminophosphine, phosphite ester amide halogen A process for the preparation of cargoes and aminophosphine halides, wherein the auxiliary base and b) acid form salts at temperatures at which the desired product is hardly degraded during the separation of the liquid salts, and c) The salt forms two liquid phases which are immiscible with the solution of the desired product in the desired product or a suitable solvent. |
