Abstract

A process for preparing a triazine compound represented by formula (1) including reacting a 2,4,6-trichlorotriazine, in the presence of a base, with a compound represented by the formula (2) in an organic solvent containing water and an aromatic hydrocarbon is provided.

Claims (22)

1. A process for preparing a triazine compound represented by the following formula (1) comprising: reacting 2,4,6-trichlorotriazine, in the presence of a base, with a compound represented by the following formula (2) in a solvent including water and an aromatic hydrocarbon based organic solvent:

R 1 R 2 NH  Formula (2):

wherein, R 1 represents an alkyl group, an aryl group or a heterocyclic group that may be substituted, and R 2 represents a hydrogen atom, or an alkyl group, an aryl group or a heterocyclic group that may be substituted.

2. The process for preparing a triazine compound according to claim 1 , wherein in the formula (1), R 1 represents an alkyl group and R 2 represents a hydrogen atom or an alkyl group.

3. The process for preparing a triazine compound according to claim 1 , wherein the aromatic hydrocarbon based organic solvent is toluene.

4. The process for preparing a triazine compound according to claim 2 , wherein the aromatic hydrocarbon based organic solvent is toluene.

5. The process for preparing a triazine compound according to claim 1 , wherein an inorganic base is used as the base.

6. The process for preparing a triazine compound according to claim 5 , wherein a sodium hydroxide, a potassium hydroxide or a combination thereof is used as the inorganic base.

7. The process for preparing a triazine compound according to claim 1 , wherein the base is used in an amount of an equimolar amount to an amount 10 times in molar ratio based on the 2,4,6-trichlorotriazine.

8. The process for preparing a triazine compound according to claim 1 , wherein the base and water are added after adding the compound represented by the formula (2) to a mixture of 2,4,6-trichlorotriazine and the aromatic hydrocarbon based organic solvent.

9. The process for preparing a triazine compound according to claim 1 , wherein after adding a part of the compound represented by the formula (2) to a mixture of 2,4,6-trichlorotriazine and the aromatic hydrocarbon based organic solvent in advance, the remaining compound represented by the formula (2) and the base are simultaneously added.

10. The process for preparing a triazine compound according to claim 1 , wherein after adding the base and water to a mixture of 2,4,6-trichlorotriazine and the aromatic hydrocarbon based organic solvent, the compound represented by formula (2) is added thereto.

11. The process for preparing a triazine compound according to claim 1 , wherein to a mixture of 2,4,6-trichlorotriazine and the aromatic hydrocarbon based organic solvent, water is added and thereafter, the base and the compound represented by the formula (2) are added.

12. The process for preparing a triazine compound according to claim 1 , wherein HCl is neutralized by adding an excess of the compound represented by the formula (2).

13. The process for preparing a triazine compound according to claim 8 , wherein an inorganic base is used as the base.

14. The process for preparing a triazine compound according to claim 9 , wherein an inorganic base is used as the base.

15. The process for preparing a triazine compound according to claim 10 , wherein an inorganic base is used as the base.

16. The process for preparing a triazine compound according to claim 11 , wherein an inorganic base is used as the base.

17. The process for preparing a triazine compound according to claim 8 , wherein the aromatic hydrocarbon based organic solvent is toluene.

18. The process for preparing a triazine compound according to claim 9 , wherein the aromatic hydrocarbon based organic solvent is toluene.

19. The process for preparing a triazine compound according to claim 10 , wherein the aromatic hydrocarbon based organic solvent is toluene.

20. The process for preparing a triazine compound according to claim 11 , wherein the aromatic hydrocarbon based organic solvent is toluene.
