Abstract

PARA LA OBTENCION DE CIANAMIDA DE CALCIO POR REACCION DE UREA CON UN COMPUESTO DE CALCIO QUE CONTIENE OXIGENO EN AL MENOS DOS ETAPAS A) EN UNA PRIMERA ETAPA LOS COMPONENTES REACCIONAN POR CONDENSACION Y/O CIRCULACION O COLOCANDOLOS EN UNA SUPERFICIE CALIENTE A TEMPERATURAS ENTRE 120 Y 500 C HASTA QUE SE FORMA UN SOLIDO, Y B) A CONTINUACION LA MEZCLA SOLIDA FORMADA SE CALCINA A TEMPERATURAS DE 600 A 900 C. DE ESTA MANERA SE CONSIGUEN ELEVADAS PRODUCCIONES Y RENDIMIENTOS DE CIANAMIDA DE CALCIO, SIN QUE SEA NECESARIO UN TRATAMIENTO COMPLICADO DEL PRODUCTO DESPUES DE LA PRIMERA O SEGUNDA ETAPA.
