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 9):
The process according to  claim 1 , wherein the process further comprises preparing the at least one (thio)phosphoric acid derivative (1a),\n wherein the (thio)phosphoric acid triamides according to general formula (I) are prepared by reacting\n at least one N-hydrocarbylamino(thio)phosphoryl dichloride according to general formula (III) \n wherein X 1 , R 1 , and R 2  are as defined in  claim 1 with 1) at least one amine according to general formula HNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and/or 2) at least one amide according to general formula MNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and M is an alkali metal; in at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents, to obtain a product mixture (1.1) comprising (1.1a) at least one (thio)phosphoric acid triamide according to general formula (I), wherein X 1 , R 1 , R 2 , R 3 , R 4 , R 5 , and R 6  are as defined in  claim 1 ; (1.1b) 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 and (1.1c) at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents; and wherein the (thio)phosphoric acid ester amides according to general formula (IIa) are prepared by reacting\n at least one O-hydrocarbyloxy(thio)phosphoryl dichloride according to general formula (IV) \n wherein X 2  and R 7  are as defined in  claim 1 , with 1) at least one amine according to general formula HNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and/or 2) at least one amide according to general formula MNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and M is an alkali metal; in at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents, to obtain a product mixture (1.2) comprising (1.2a) at least one (thio)phosphoric acid ester amide according to general formula (IIa),\n wherein X 2 , R 7 , R 8 , R 9 , R 10 , and R 11  are as defined in  claim 1 ; \n (1.2b) at least one salt selected from the group consisting of\n (b1) ammonium salts according to general formula H 2 NR 16R170  \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 and (1.2c) at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents; and wherein the (thio)phosphoric acid ester amides according to general formula (IIb) are prepared by reacting\n at least one O-hydrocarbyloxy(thio)phosphoryl dichloride according to general formula (V) \n wherein X 3  and R 12  are as defined in  claim 1 , with 1) at least one amine according to general formula HNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and/or 2) at least one amide according to general formula MNR 16 R 17 , wherein R 16  and R 17  are independently of each other selected from the group consisting of H and C 1 -C 4 -alkyl, and M is an alkali metal; and with 3) at least one alcohol according to general formula HOR 15 , wherein R 15  is as defined in  claim 1 and/or 4) at least one alcoholate according to general formula MOR 15 , wherein R 15  is as defined in  claim 1 ; in at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents, to obtain a product mixture (1.3) comprising (1.3a) at least one (thio)phosphoric acid ester amide according to general formula (IIb), wherein X 3 , R 12 , R 13 , R 14 , and R 15  are as defined in  claim 1 ; (1.3b) 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 and (1.3c) at least one polar solvent, which is selected from the group consisting of ester solvents and ether solvents.
