Abstract: The invention relates to a method of separating acids from reaction mixtures comprising at least one product of value which is of low water solubility, by means of at least one apolar amine as auxiliary base, said method comprising the following steps: a) reacting the auxiliary base with the acid to form a salt; b) reacting the salt formed in step a) with a further base which takes over the acid while releasing the auxiliary base; c) extracting the mixture obtained in step b) with water or an aqueous medium, the salt of the further base dissolving in the aqueous phase, and the product of value, or the solution of the product of value in a suitable solvent, and the auxiliary base forming at least one separate, non-aqueous phase; and d) removing, by distillation, the auxiliary base and/or at least part of any solvent present from the at least one non-aqueous phase obtained in step c), in the course of which two immiscible liquid phases may be formed. The invention further relates to a process for preparing thiophosphoramides, to the thiophosphoramides obtainable by this process, and to the use of these thiophosphoramides as an addition to urea-containing mineral and/or organic-mineral fertilizers.
