Patent ID: 7786324

Claim:
A method for producing a purified N-alkylborazine compound comprising: reacting a) an alkali boron hydride represented by ABH 4 (A represents lithium atom, sodium atom or potassium atom) and an amine salt represented by (RNH 3 ) n X (R represents hydrogen atom or alkyl group, X represents sulfate group or halogen atom, and n is 1, or 2), or b) diborane (B 2 H 6 ) and an amine represented by RNH 2 (R represents hydrogen atom or alkyl group) to obtain an N-alkylborazine compound of the following formula: in which R is alkyl; purifying by distillation the N-alkylborazine compound; and separating undesired compounds from the N-alkylborazine compound by filtration to obtain N-alkylborazine having a purity not lower than 99.9% by mass.
