Abstract
Procedimiento mejorado para la obtención de cloruro de cianurilo en forma sólida o líquida, a partir de la mezcla de reacción que resulta de la trimerización de cloruro de cianógeno, caracterizado porque la mezcla gaseosa de reacción es introducida en una combinación de aparatos, consistente esencialmente en una columna de extracción y un condensador conectado detrás de ella, de preferencia un condensador de cabezas, preferentemente por encima de la columna de extracción, y se mantiene el colector de la columna de extracción a la temperatura de ebullición del cloruro de cianurilo, después de lo cual se enfría el cloruro de cianurilo contenido en la mezcla gaseosa de reacción a la salida del condensador a una temperatura en el margen desde 146 hasta 190ºC, y para la obtención de cloruro de cianurilo en forma líquida, el cloruro de cianurilo líquido se retira como tal en el extremo inferior de la columna de extracción y/o se introduce intermedio, en una torre de rociado y se rocía en ella, después de los cual se retira el cloruro de cianurilo sólido, en forma de granos finos, en el fondo de la torre de rociado.
