Abstract

METODO PARA LA PREPARACION O ACTIVACION DE CATALIZADORES DIPEPTIDOS SOLIDOS. COMPRENDE LA PREPARACION DEL CATALIZADOR DIPEPTIDO DE CICLO (D-FENILALANIL-D-HISTIDINA) Y CICLO (L-FENILALANIL-L-HISTIDINA), MEDIANTE UNA SINTESIS DE PEPTIDOS CONVENCIONAL; DISOLUCION DEL CATALIZADOR EN UN ALCANOL INFERIOR DE 1 A 10 ATOMOS DE CARBONO POR CALENTAMIENTO A REFLUJO, Y EVAPORACION RAPIDA DEL DISOLVENTE, MEDIANTE SECADO POR ATOMIZACION, CON LO QUE SE OBTIENE UN SOLIDO PREDOMINANTEMENTE AMORFO. ESTOS CATALIZADORES TIENEN APLICACIONES EN SINTESIS ORGANICA PARA LA CIANOHIDRINACION DE ALDEHIDOS Y CETONAS.
