NBPT SOLUTIONS FOR PREPARING UREASE INHIITED UREA FERTILIZERS PREPARED FROM N-ALKYL; N, N-ALKYL; AND N-ALKYL-N-ALKOXY AMINO ALCOHOLS

Solutions are prepared by dissolving N-(n-butyl)-thiophosphoric triamide (NBPT) in one or more N-alkyl amino alcohols, N, N-dialkyl amino alcohols, N-alkyl-N-alkoxy amino alcohols, and mixtures thereof. The solutions may be used in urea fertilizers to reduce nitrogen volatilization, or to reduce the...

More Information
Summary:Solutions are prepared by dissolving N-(n-butyl)-thiophosphoric triamide (NBPT) in one or more N-alkyl amino alcohols, N, N-dialkyl amino alcohols, N-alkyl-N-alkoxy amino alcohols, and mixtures thereof. The solutions may be used in urea fertilizers to reduce nitrogen volatilization, or to reduce the odor of animal waste. Methods of preparing urea fertilizers and the resultant products are also described. Des solutions sont préparées par dissolution de triamide N-(n-butyl)-thiophosphorique (NBPT) dans un ou plusieurs amino-alcools N-alkyliques, N,N-dialkyliques, N-alkyl-N-alcoxyliques et dans des mélanges de ceux-ci. Lesdites solutions peuvent être utilisées dans des engrais à base d'urée pour limiter la volatilisation de l'azote ou l'odeur de déchets animaux. L'invention concerne également des procédés de préparation d'engrais à base d'urée et les produits résultants.
