Abstract

PROCEDIMIENTO PARA PREPARAR DE MANERA CONTINUA SOLUCIONES ACUOSAS DE TIOCIANATO DE AMONIO. COMPRENDE: A) HACER REACCIONAR AMONIACO Y SULFURO DE CARBONO, EN AGUA, ENTRE 90 Y 150JC Y A UNA PRESION ENTRE 2 Y 7 BARES, PARA FORMAR UNA SOLUCION DE TIOCIANATO DE AMONIO QUE SE ELIMINA DE FORMA CONTINUA; B) LLEVAR LA SOLUCION DE TIOCIANATO DE AMONIO A PRESION NORMAL; C) DISOLVER LOS GASES DESPRENDIDOS EN LA ETAPA A); Y D) APORTAR LOS GASES DE LA ETAPA C) AL PROCESO DE SOLUCION. EL AMONICAO SE DOSIFICA EN ESTADO LIQUIDO Y EL SULFURO DE CARBONO EN ESTADO GASEOSO. SE UTILIZA PARA FORMAR SOLUCIONES DE POLIACRILONITRILO.
