Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DISPERSIONES DE DINITROANTRAQUINONAS. SE PONE EN CONTACTO DINITROANTRAQUINONA EN FORMA FINAMENTE REPARTIDA, CON AGENTES TENSOACTIVOS CATIONICOS, NO IONICOS Y SOBRE TODO ANIONICOS, COMO AMINAS CUATERNARIAS DE CADENA LARGA Y/O OXETILADAS Y LIGNINSULFATOS, Y AGUA Y/O LIQUIDOS ORGANICOS MISCIBLES CON AGUA CUYO PUNTO DE EBULLICION SE ENCUENTRA POR ENCIMA DE LOS 80 C. LAS DINITROANTRAQUINONAS A UTILIZAR DEBEN TENER, EN UN 80 POR 100 EN PESO, SUS PARTICULAS CON UNA GRANULOMETRIA INFERIOR A 10 PM. SE UTILIZAN EN PROCEDIMIENTO PARA LA OBTENCION DE CELULOSA A PARTIR DE MATERIALES LIGNOCELULOSICOS.PROCEDURE FOR OBTAINING DISPERSIONS OF DINITROANTHRAQUINONES. DINITROANTHRAQUINONE IN FINELY DISTRIBUTED FORM IS CONTACTED WITH CATIONIC, NON-IONIC AND ESPECIALLY ANIONIC SURFACE-ACTIVE AGENTS, SUCH AS LONG-CHAIN AND/OR OXETHYLATED QUATERNARY AMINES AND LIGNINSULFATES, AND WATER AND/OR WATER-MISCIBLE ORGANIC LIQUIDS WHOSE BOILING POINT IS FOUND ABOVE 80 C. THE DINITROANTHRAQUINONES TO BE USED SHOULD HAVE, IN 80 PER 100 BY WEIGHT, THEIR PARTICLES WITH A GRANULOMETRY LESS THAN 10 PM. THEY ARE USED IN PROCEDURE FOR OBTAINING CELLULOSE FROM LIGNOCELLULOSIC MATERIALS.
