Abstract
Una composición inhibidora de incrustaciones para inhibir la formación de incrustaciones de sales de calcio en mezclas acuosas alcalinas de procesos químicos de fabricación de pulpa en los cuales dicha composición que se agrega al digestor de dicho proceso químico de fabricación de pulpa, comprende una cantidad efectiva como inhibidora de incrustaciones de por lo menos un fosfonato seleccionado entre compuestos que presentan la siguiente fórmula (1) X2NCH2PO3M2, compuestos que presentan la fórmula (2) óxidos de amina de fosfonatos de fórmula (1) o mezclas de los mismos; donde M se selecciona independientemente entre hidrógeno, metales alcalinos, metales alcalino-térreos de amonio, X se selecciona independientemente entre H, R o -CH2PO3M2 donde R es un grupo alquilo o un grupo alquilo sustituido con -NX2 que tiene entre 2 y 6 átomos de carbono, R' es un grupo alquilo que tiene entre 1 a 17 átomos de carbono y R' es un grupo optativamente ramificado y optativamente insaturado, e Y se selecciona entre -PO3M2, H o R'; con la condición que cuando dicho fosfonato es N(CH2PO3M2)3, la cantidad de dicho fosfonato basado en el ácido activo es mayor que 25 ppm basado en el peso de licor total cargado a dicho digestor. También se describe un método para inhibir la formación de incrustaciones de sales de calcio en proceso químicos alcalinos de fabricación de pulpa, para la obtención de papel.
