Abstract:
PROBLEM TO BE SOLVED: To improve nitrogen utilization when employing urease inhibitors in fertilization with urea or urea-containing fertilizers, and to reduce the required application rates of urease inhibitors.SOLUTION: The invention relates to: preparations with improved urease-inhibitory effect which comprise at least two different (thio)phosphoric triamides; and urea-containing fertilizers which comprise the preparations. The invention further relates to: a method of preparing the preparations; the use of the preparations in fertilization with the urea-containing fertilizers; and the use of the urea-containing fertilizers which comprise the preparations in agriculture or in horticulture.
Abstract:
A process for the removal of acids from reaction mixtures, comprising at least one product of value which is sparingly soluble in water, by at least one unpolar amine as an auxiliary base, which includes: a) reacting the auxiliary base with the acid with formation of a salt; b) reacting the salt formed in step 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, wherein 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 nonaqueous phase; and d) removal by distillation of at least part of any solvent present from the at least one nonaqueous phase obtained in step c), to form two nonmiscible liquid phases.
