Abstract
Perfeccionamientos en la obtención de compuestos nitrogenados aromáticosque incluyen un procedimiento para la preparación de tricarbimidas aromáticas monocíclicasque comprende el hacer reaccionar una proporción molecular de un triamino-compuesto aromático primario de la fórmula general **(Ver fórmula)** en la que R es hidrógenoun grupo alkilo o éterdisuelto en un disolvente orgánico volátil e inerte para aquélcon 15 proporciones molecularespor lo menos de fosgeno disuelto en un disolvente orgánico volátil e inerte para el mismoy en calentar la suspensión resultante a una temperatura no inferior a unos 90ºC.a la vez que se hace pasar por el interior de la misma una corriente de fosgeno en condiciones que favorezcan la eliminación del cloruro de hidrógeno desprendidohasta completar la formación de la correspondiente tricarbimida aromáticas monocíclica.Improvements in obtaining aromatic nitrogenous compounds that include a process for the preparation of monocyclic aromatic tricarbimides that comprises reacting a molecular proportion of a primary aromatic triamino-compound of the general formula ** (See formula) ** in which R is hydrogeno alkyl or ether group dissolved in a volatile organic solvent and inert to that one with at least 15 molecular proportions of phosgene dissolved in a volatile organic solvent and inert thereto and in heating the resulting suspension to a temperature not lower than about 90 ° C. at the same time as it makes a stream of phosgene pass through it under conditions that favor the elimination of the hydrogen chloride evolved until the formation of the corresponding monocyclic aromatic tricarbimide is completed.
