    摘要: A method for producing phosphoryl triamide OP(NH2)3 or thiophosphoryl triamide SP(NH2)3, in which: a) phosphoryl trichloride OPCl3 or thiophosphoryl trichloride SPCl3, respectively, is reacted with gaseous ammonia in an apolar liquid phase to give a first precipitate comprising, respectively, phosphoryl triamide or thiophosphoryl triamide, and ammonium chloride, and b) the first precipitate is treated with sodium carbonate or potassium carbonate, in a polar organic liquid phase, to give a second precipitate comprising NaCl and the phosphoryl triamide or thiophosphoryl triamide remaining in said polar organic liquid phase, and the second precipitate is separated from the polar organic liquid phase, the latter possibly undergoing a further concentration step to enrich it in phosphoryl triamide or thiophosphoryl triamide.

    摘要: A use of 1,9-decanediol in inhibiting ammonia volatilization from soil is provided. It is found that 1,9-decanediol has dual regulation effects, not only significantly inhibiting ammonia volatilization from soil, but also effectively inhibiting nitrification process, which plays synergistic effects. As a fat-soluble substance, 1,9-decanediol has high stability in soil and is not easy to be separated from nitrogen fertilizer. 1,9-decanediol, as a plant root exudate, also has advantages of being green, safe, and pollution-free, which provides a new method and an idea to expand an application field of 1,9-decanediol and improve an industrial application value of 1,9-decanediol.
