Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA ALQUILACION DE IMIDAS QUE ESTA CARACTERIZADO POR EL HECHO DE QUE LAS IMIDAS SE HACEN REACCIONAR CON UN CARBONATO DE DIALQUILO, EN EL ESTADO LIQUIDO, A UNA TEMPERATURA DE ENTRE 100 (GRADOS) C Y 250 (GRADOS) C Y A UNA PRESION DE ENTRE 0 Y 60 ATMOSFERAS EN PRESENCIA DE UN CATALIZADOR BASICO. LOS REACTIVOS DE CARBONATO DE DIALQUILO NO SON MUY TOXICOS Y SON TERMICAMENTE ESTABLES Y SU USO COMO AGENTES DE ALQUILACION HACEN POSIBLE PRODUCIR PRODUCTOS RESIDUALES CON UN CONTENIDO SALINO INSIGNIFICANTE.
