摘要 |
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. |
