BUFFERED AMINO ALCOHOL SOLUTIONS OF N-(N-BUTYL)THIOPHOSPHORIC TRIAMIDE (NBPT) AND UREA FERTILIZERS USING SUCH SOLUTIONS AS UREASE INHIBITORS

摘要

Disclosed herein is a method of preparing a solution for use in reducing the volatility of urea fertilizers comprising dissolving N-(n-butyl)-thiophosphoric triamide (NBPT) in a mixture of an amino alcohol having the formula 1-(H)x-N-((CH2)m-OH)n where m is 1-3, x is 0 or 1, and n is 2 when x is 1 and 3 when x is 0: or the formula 2-(H)y-N-((CH2)-CHOH-CH3)z such that the length of the carbon chain where the secondary hydroxyl group is located is 3, y is 0 or 1, and z is 2 when y is 1 and 3 when y is 0, and a carboxylic acid having 6 or fewer carbon atoms to form an NBPT solution.
