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.

Claim (Index 1):
A process for isolating\n at least one (thio)phosphoric acid derivative (1a), which has a melting point of at least 70\u00b0 C., and which is selected from\n (i) \n (thio)phosphoric acid triamides according to general formula (I) \n wherein X 1  is O or S; R 1  is C 1 -C 20 -alkyl, C 3 -C 20 -cycloalkyl, C 6 -C 20 -aryl, C 6 -C 20 -aryl-C 1 -C 4 -alkyl, or C 1 -C 6 -(di)alkylaminocarbonyl; R 2  is H, C 1 -C 20 -alkyl, C 3 -C 20 -cycloalkyl, C 6 -C 20 -aryl, C 6 -C 20 -aryl-C 1 -C 4 -alkyl, or C 1 -C 6 -(di)alkylaminocarbonyl; or R 1  and R 2  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 N, O, and S; and R 3 , R 4 , R 5 , and R 6  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl; and (ii) (thio)phosphoric acid ester amides according to any one of general formula (IIa) wherein X 2  is O or S; R 7  is C 1 -C 20 -alkyl, C 3 -C 20 -cycloalkyl, C 6 -C 20 -aryl, C 6 -C 20 -aryl-C 1 -C 4 -alkyl, or C 1 -C 6 -(di)alkylaminocarbonyl; and R 8 , R 9 , R 10 , and are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl; or general formula (IIb) wherein X 3  is O or S; R 12  is C 1 -C 20 -alkyl, C 3 -C 20 -cycloalkyl, C 6 -C 20 -aryl, C 6 -C 20 -aryl-C 1 -C 4 -alkyl, or C 1 -C 6 -(di)alkylaminocarbonyl; R 15  is C 1 -C 20 -alkyl, C 3 -C 20 -cycloalkyl, C 6 -C 20 -aryl, C 6 -C 20 -aryl-C 1 -C 4 -alkyl, or C 1 -C 6 -(di)alkylaminocarbonyl; and R 13  and R 14  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl; from a product mixture (1) comprising\n (1a) the at least one (thio)phosphoric acid derivative; \n (1b) at least one salt selected from the group consisting of\n (b1) ammonium salts according to general formula H 2 NR 16 R 17 Cl \n wherein \n R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl; \n and \n (b2) alkali metal chlorides; \n \n (1c) at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents; and \n (1d) optionally at least one HCl scavenger; \n wherein the process comprises at least-the steps of\n (a) heating the product mixture (1) to a temperature, which is sufficient for at least partly dissolving the at least one (thio)phosphoric acid derivative (1a); \n (b) separating solid material from the heated product mixture (1) to remove the at least one salt (1b) and to obtain a solution comprising the at least one (thio)phosphoric acid derivative (1a) and the at least one polar solvent (1c) 7  and optionally the at least one HCl scavenger (1d); \n (c) causing solids formation of the at least one (thio)phosphoric acid derivative (1a) from the obtained solution by partly evaporating the at least one solvent (1c) from the solution and/or cooling the solution; and \n (d) isolating the solid material.
