Abstract

SE PRESENTAN COMPOSICIONES Y METODOS PARA INHIBIR LA POLIMERIZACION DE MONOMEROS AROMATICOS DE VINIL EN SISTEMAS DE PROCESAMIENTO LIBRES DE OXIGENO. LAS COMPOSICIONES COMPRENDEN UN COMPUESTO DE OXIMO Y UN COMPUESTO DE HIDROXILAMINO Y, ALTERNATIVAMENTE, UN COMPUESTO DE OXIMO O UN DINITROFENOL, UN COMPUESTO DE HIDROXILAMINO Y UN COMPUESTO DE FENILENODIAMINO. LOS METODOS COMPRENDEN LA ADICION DE LAS COMPOSICIONES AL MONOMERO AROMATICO DE VINIL EN UNA CANTIDAD QUE OSCILA ENTRE 1 Y 10000 POR MILLON DE PARTES DE MONOMERO. TAMBIEN SE PRESENTA UN METODO MEJORADO PARA INHIBIR LA POLIMERIZACION DE MONOMEROS AROMATICOS DE VINIL CON UN COMPUESTO DE HIDROXILAMINO. LA MEJORA SUMINISTRA LA ADICION DE UNA CANTIDAD CATALITICA DE UN COMPUESTO DE FENILENODIAMINO AL SISTEMA DE MONOMEROS AROMATICOS DE VINIL MIENTRAS QUE REEMPLAZA CUALQUIER COMPUESTO DE FENILENODIAMINO PERDIDO COMO RESULTADO DE LA ELIMINACION FISICA DEL SISTEMA POR MEDIO DE UNA CORRIENTE DE DESECHO.
