Abstract (en)
[origin: CA3214284A1] Disclosed is a method for producing phosphoryl triamide OP(NH2)3 or thiophosphoryl triamide SP(NH2)3, wherein a) phosphoryl trichloride OPCI3 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, b) said first precipitate is treated with sodium carbonate or potassium carbonate, preferably with sodium carbonate, in a polar organic liquid phase, to give a second precipitate comprising NaCI and the remaining phosphoryl triamide or thiophosphoryl triamide in said polar organic liquid phase, and said second precipitate is separated from said polar organic liquid phase, said phase optionally being further subjected to a concentration step to enrich it in phosphoryl triamide or thiophosphoryl triamide.
