Abstract
UN PROCESO PARA LA OBTENCION DE COLORANTES AL AZUFRE EN FORMA LEUCO SECOS. COMPRENDE REDUCIR UN COLORANTE AL AZUFRE (S) EN UN MEDIO ACUOSO CON UN COMPUESTO CARBONILICO REDUCTOR EN PRESENCIA DE UN HIDROXIDO DE METAL ALCALINO Y OPCIONALMENTE DE UN (BI)SULFITO DE METAL ALCALINO A TEMPERATURAS POR ENCIMA DE 60GC: Y SECAR LA MEZCLA DE REACCION. SE OBTIENEN COLORANTES AL AZUFRE (L) MUY ESTABLES, QUE ESTAN PRACTICAMENTE LIBRES DE SULFUROS Y POLISULFUROS, SON FACIL Y COMPLETAMENTE SOLUBLES EN AGUA Y SON UTILIZABLES PARA EL TEÑIDO DE SUBSTRATOS TEÑIBLES CON COLORANTES AL AZUFRE, POR LO QUE UN DESARROLLO MOLESTO DE HSI2 SCS O UNA PRESENCIA MOLESTA DE SULFUROS INORGANICOS EN EL AGUA RESIDUAL PUEDEN EVITARSE EFICIENTEMENTE.
