Abstract: A composition comprising: (A) a mixture comprising at least one (thio)phosphoric acid triamide according to the general formula (I) R1R2N—P(X)(NH2)2, wherein X is oxygen or sulfur; R1 is a C1 to C20 alkyl, C3 to C20 cycloalkyl, C6 to C20 aryl, or dialkylaminocarbonyl group; R2 is H, or R1 and R2 together with the nitrogen atom linking them define a 5- or 6-membered saturated or unsaturated heterocyclic radical, which optionally comprises 1 or 2 further heteroatoms selected from the group consisting of nitrogen, oxygen, and sulfur, and (L1) at least one amine selected from the group consisting of (L10), (L11), (L12), (L13), (L14), (L15), (L16), (L17), (L18), (L19), (L20), (L21), (L22), (L23), (L24), and (L29).

Abstract: Provided herein is a process for isolating at least one (thio)phosphoric acid derivative, which has a boiling point of at least 70° C., from a product mixture including the at least one (thio)phosphoric acid derivative, at least one salt selected from ammonium salts and alkali metal chlorides, at least one polar solvent selected from the group consisting of ester solvents and ether solvents, and optionally at least one HCl scavenger; wherein the process is based on first dissolving the (thio)phosphoric acid derivative to be able to remove the at least one salt, and then causing solids formation of the (thio)phosphoric acid derivative.

Abstract: Provided herein is a use of a high-boiling solvent in a mixture comprising a (thio)phosphoric acid derivative and a process including the addition of a high-boiling solvent to a mixture comprising a (thio)phosphoric acid derivative to recover the (thio)phosphoric acid from the mixture by an evaporation process.
