Abstract

PROCEDIMIENTO DE MOLIENDA DE QUINACRIDONA CRUDA CON HIDRATOS DE BORAX Y UN ALCOHOL O UN POLIETILENGLICOL.LAS QUINACRIDONAS ADECUADAS A ESTE PROCEDIMIENTO INCLUYEN LA QUINACRIDONA Y LAS QUINACRIDONAS DE FORMULA (I), DONDE R1 Y R2, IGUALES O DIFERENTES, SE ESCOGEN ENTRE H, F, CL, CH3 Y OCH3, CONSISTIENDO EL PROCEDIMIENTO EN LA MOLIENDA DEL PIGMENTO CRUDO EN UN MOLINO DE BOLAS OCILINDROS JUNTO CON 3 A 10 PARTES, EN PESO, DE PIGMENTO DE PENTAHIDRATO DE BORAX Y 5 A 40, EN PESO DE PIGMENTO, DE UN ALCOHOL MONOHIDRICO CON 4 A 8 ATOMOS DE CARBONO O DE UN POLIETILENGLICOL CON PESO MOLECULAR ENTRE 150 Y 600. EL POLVO RESULTANTE SE SUSPENDE EN AGUA Y SE TRATA CON ACIDO DILUIDO A TEMPERATURA ELEVADA PARA ELIMINAR EL HIERRO PROCEDENTE DE LOS ELEMENTOS DE LA MOLIENDA. OPCIONALMENTE, SE AGREGA UN AGENTE DE ACABADO DURANTE EL TRATAMIENTO ACIDO.
