Abstract

Procedimiento de preparar una combinación que tiene la fórmula estructural **(ver fórmula)** en la cual por lo menos una de las R representa un radical alkílico y las restantes R y todas las R1 son seleccionadas del grupo compuesto por el átomo de hidrógeno y radicales hidrocarbónicos monovalentes; caracterizado porque un ácido benzoico sustituído (o su correspondiente halogenuro anhídrido amida o un éster) se hace reaccionar con una alfa-gamma-alkileno-diamina (o una sal de la misma) en presencia de un catalizador de deshidratación.Procedure of preparing a combination that has the structural formula ** (see formula) ** in which at least one of the R represents an alkyl radical and the remaining R and all R1 are selected from the group consisting of the hydrogen atom and monovalent hydrocarbon radicals; characterized in that a substituted benzoic acid (or its corresponding amide anhydride halide or an ester) is reacted with an alpha-gamma-alkylene-diamine (or a salt thereof) in the presence of a dehydration catalyst.
