Abstract

PROCEDIMIENTO DE OBTENCION DE COLORANTES DE DISPERSION DE PIRIDONA. CONSTA DE LAS SIGUIENTES OPERACIONES: 1. REACCION DEL ESTER BENCILICO DEL ACIDO P-AMINOBENZOICO DIAZOTADO CON 1-A-BUTIL-3-CIANO-4-METIL-6-HIDROXIPIRIDONA-2, OBTENIENDOSE LA MODIFICACION ALFA DEL COMPUESTO (I). 2. TRANSFORMAR LA MODIFICACION ALFA OBTENIDA EN LA GAMMA O DELTA DEL COMPUESTO I; DICHA TRANSFORMACION SE EFECTUA EN UN MEDIO ACUOSO A UNA TEMPERATURA DE AL MENOS 130GC; EL MANTENIMIENTO PUEDE EFECTUARSE DURANTE 1 A 4 HORAS. LA SUSPENSION DEBE CONTENER UN AGENTE TENSOACTIVO ANIOTICO. UNA VEZ OBTENIDA LA FORMA DE ESPOLVOREA LA SUSPENSION ANTES DE SOMETERLA A TRATAMIENTO TERMICO. *FORMULA*PROCEDURE FOR OBTAINING PYRIDONE DISPERSION DYES. IT CONSISTS OF THE FOLLOWING OPERATIONS: 1. REACTION OF THE BENZYL ESTER OF DIAZOTED P-AMINOBENZOIC ACID WITH 1-A-BUTIL-3-CYANO-4-METHYL-6-HYDROXYPYRIDONE-2, OBTAINING THE ALPHA MODIFICATION OF THE COMPOUND (I). 2. TRANSFORM THE ALPHA MODIFICATION OBTAINED INTO THE GAMMA OR DELTA OF COMPOUND I; SUCH TRANSFORMATION IS CARRIED OUT IN AN AQUEOUS MEDIUM AT A TEMPERATURE OF AT LEAST 130GC; MAINTENANCE CAN BE DONE FOR 1 TO 4 HOURS. THE SUSPENSION SHOULD CONTAIN AN ANIOTIC SURFACTIVE AGENT. ONCE THE FORM IS OBTAINED, SPRINKLE THE SUSPENSION BEFORE SUBJECTING IT TO THERMAL TREATMENT. *FORMULA*
