    Abstract: Composition comprises at least two different (thio)phosphoric acidtriamide (I). Composition comprises at least two different (thio) phosphoric acidtriamide (I) of formula (R 1R 2N-P(X)(NH 2) 2). Either R 1, R 2H, 1-10C-alkyl-, 3-10C-cycloalkyl-, 6-10C-aryl- or dialkylaminocarbonyl; or N(R 1+R 2) : 5-6 membered optionally saturated heterocycle, optionally containing 1 or 2 heteroatoms that are replaced by N, O or S; and X : O or S. Independent claims are included for: (1) the preparation of the composition comprising mixing at least two (thio)phosphoricacidtriamide together or transferring thiophosphorylchloride with a mixture of at least two different primary- or secondary amine and subsequently with ammonia; and (2) a urea containing fertilizer comprising the composition.

    Abstract: Disclosed is a process for the removal of acids from reaction mixtures, comprising at least one product of value which is sparingly soluble in water, by means of at least one unpolar amine as auxiliary base that is not miscible with the product of value, comprising the following steps: a) reacting the auxiliary base with the acid with formation of a salt; b) reacting the salt formed in a) with a further base which accepts the acid with liberation of the auxiliary base and combines with the acid to be accepted from the auxiliary base to form a salt which is very readily soluble in water; c) extraction of the mixture obtained in step b) with water or an aqueous medium, where the salt of the further base dissolves 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 form at least one separate non-aqueous phase; and d) removal by distillation of at least part of any solvent present from the at least one non-aqueous phase obtained in step c), to form two non-miscible liquid phases.
