Abstract

UNA TERCERA QUETONA O ALDEHIDO SE AÑADE A UNA MEZCLA BINARIA DE ALDEHIDOS Y/O KETONAS USANDAS EN LA PREPARACION DE MEZCLAS DE PIRIDINA O PIRIDINAS SUSTITUIDAS DE ALKIL EN UN PROCESO CONTINUO DE AMPLIA ESCALA. LA CANTIDAD DEL TERCER COMPONENTE SE AJUSTA APROPIADAMENTE MEDIANTE LO CUAL LAS RELACIONES RELATIVAS DE LOS PRODUCTOS SE AJUSTAN Y LA PRODUCCION TOTAL DE PIRIDINAS O PIRIDINAS ALKIL-SUSTITUIDAS ES ALTA, TODO ELLO SIN NINGUNA PARADA DE LA PLANTA. EN UN SISTEMA MAS APROPIADO, EL PROPIONALDEHIDO SE AÑADE A UNA MEZCLA BINARIA DE ACETALDEHIDO Y FORMALDEHIDO PARA PRODUCIR SORPRENDENTEMENTE ALTAS CANTIDADES DE BETA-PIRIDINA Y PIRIDINA.
