| titleOfInvention | Method for separating N-substituted melamine derivative |
| abstract | (57) Abstract: An object of the present invention is to produce a salt by acid-treating a mixture of two or more N-substituted melamine derivatives by utilizing its basicity, and to produce water of the produced salt. , One or two or more N-substituted melamine derivatives are separated from the mixture by separating them by utilizing the difference in solubility in solvents such as organic solvents, crystallinity, etc., and then neutralizing them if desired. Isolated in pure form, as fine chemical intermediates for various agricultural chemicals, pharmaceuticals, dyes, paints, various resin materials, It is intended to provide a method for industrially easily supplying a pure N-substituted melamine derivative which is a useful compound group that can be widely used as a flame retardant material. SOLUTION: Melamine (2,4,6-triamino- 1,3,5-triazine), a mixture of two or more kinds of N-substituted melamine derivatives having a substituent on the amino group is treated with an acid to form a salt, and one or two kinds are produced from the mixture of the formed salts. The present invention relates to a novel method for separating N-substituted melamine derivatives, which comprises isolating one or more N-substituted melamine derivatives. |
