A method for preparing a desired benzoxazine compound comprises preparing a substantially homogenous reaction mixture that includes a phenolic compound, a primary amine, and an aldehyde, but no solvent other than for the solvency which the reactants may have for each other. Following its preparation the reaction mixture is maintained at a temperature for a period sufficient to cause the reactants to combine chemically to form the desired compound.
Ce procédé de préparation de composés choisis de la benzoxazine consiste à préparer un mélange réactionnel sensiblement homogène comprenant un composé phénolique, une amine primaire et un aldéhyde, mais aucun autre solvant, car les réactifs sont mutuellement solubles. Après sa préparation, le mélange réactionnel est chauffé pendant une durée suffisante pour faire en sorte que les réactifs se combinent chimiquement pour obtenir le composé souhaité.
