Abstract

PROCEDIMIENTO PARA LA OBTENCION DE OMEGA-LACTAMAS QUE CONTIENEN DE 5 A 14 ATOMOS DE CARBONO. SE BASA EN LA REACCION DE ACIDOS CICLOALIFATICOS DE FORMULA (I), EN LA QUE N VALE DE 3 A 13, O DE LOS CORRESPONDIENTES ANHIDRIDOS, CON UN AGENTE DE NITROSACION, CUYA CONCENTRACION SE MANTIENE A NIVEL CONSTANTE MEDIANTE UNOS ELECTRODOS REDOX INTRODUCIDOS EN LA MASA DE REACCION, Y EN PRESENCIA DE UN AGENTE DESHIDRATANTE. LA REACCION MOLAR DE AGENTES DESHIDRATANTE A AGENTE DE NITROSACION OSCILA ENTRE 0,7 Y 1. LA REACCION SE LLEVA A CABO A UNA TEMPERATURA BAJA, QUE SE MANTIENE CONSTANTE EMPLEANDO LIQUIDOS INERTES QUE ELIMINAN EL CALOR DE LA REACCION POR MEDIO DE SU VAPORIZACION. ESTOS COMPUESTOS SE APLICAN PARA LA OBTENCION DE POLIMEROS. *FORMULA*
