Abstract
SE PRESENTAN CATALIZADORES ALTAMENTE ACTIVOS DE COMPLEJO DE CIANURO DE METAL DOBLE (DMC) QUE, A DIFERENCIA DE OTROS CATALIZADORES (DMC) ALTAMENTE ACTIVOS, SON SUBSTANCIALMENTE CRISTALINOS, LOS CATALIZADORES COMPRENDEN UN COMPUESTO DMC, UN AGENTE COMPLEJADOR ORGANICO, Y UNA SAL DE METAL, EN DONDE EL CATALIZADOR CONTIENE MENOS DE 0.2 MOLES DE SAL DE METAL POR MOL DE COMPUESTO DMC. LOS CATALIZADORES PUEDEN FORMARSE HACIENDO REACCIONAR SOLUCIONES ACUOSAS DE UNA SAL DE METAL Y UNA SAL DE CIANURO DE METAL EN LA PRESENCIA DE UN AGENTE COMPLEJADOR ORGANICO, EN DONDE LA SAL DE METAL SE UTILIZA EN UNA CANTIDAD EN EXCESO MENOR DE UN 100% DEL EXCESO ESTEQUIOMETRICO RELATIVO A LA CANTIDAD DE SAL DE CIANURO DE METAL. ALTERNATIVAMENTE LA SOLUCION ACUOSA PUEDE HACERSE REACCIONAR CON LA SAL DE METAL EN EXCESO PARA FORMAR UN PRECIPITADO DE CATALIZADOR Y EL PRECIPITADO SE LAVA ENTONCES CON AGUA Y CON AGENTE COMPLEJADOR PARA PRODUCIR EL PRODUCTO DE CATALIZADOR. LOS POLIOLES DE POLIETER HECHOS A PARTIR DE LOS CATALIZADORES TIENEN UNA BAJA INSATURACION Y SON UTILES PARA HACER MUCHOS TIPOS DE PRODUCTOS DE POLIURETANO.
