Abstract
PROCESO QUE COMPRENDE EL AÑADIR A UNA AMINA AROMATICA EN PRSENCIA DE HF PARA UNA ZONA DE REACCION SIMULTANEMANTE CON UN AGENTE DIAZOLIZANTE ASI COMO PARA EFECTUAR LA DIAZOTIZACION DE LA AMINA AROMATICA, DESCOMPOSICION TERMICA DE LA SAL DE DIAZONIUM RESULTANTE SUSTANCIALMENTE SEGUN ESTA SE FORMA, Y ELIMINACION DEL COMPUESTO FLUOROAROMATICO RESULTANTE DE LA ZONA DE REACCION SUSTANCIALMENTE SEGUN SE FORMA. LA AMINA Y EL AGENTE DIATOMIZANTE SE AÑADEN A LA ZONA DE REACCION EN TALES CANTIDADES Y PROPORCIONAN SUSTANCIALMENTE SEGUN SE AÑADEN Y NO SE FORMEN CONCENTRACIONES SUSTANCIALES DE AGUA EN LA ZONA DE REACCION.
