Abstract
SE PRESENTA UN PROCEDIMIENTO PARA LA PRODUCCION DE PRODUCTOS DE CONDENSACION QUE CONTIENEN GRUPOS SULFONICOS A BASE DE AMINO - S TRIACINAS CON AL MENOS DOS GRUPOS AMINO Y FORMALDEHIDO CON UN CONTENIDO EN FORMALDEHIDO LIBRE, DONDE SE SOMETE A: A) AMINO - S TRIACINA, FORMALDEHIDO, Y SULFITO EN PROPORCION MOLAR DE 1 : 1,3 HASTA 6 : 1,5 EN SOLUCION ACUOSA PARA UN VALOR DE PH DE 9,0 A 12,0, Y UNA TEMPERATURA DE 50 A 90 (GRADOS) C ASI SE CONDENSA HASTA QUE NO QUEDA NINGUN SULFITO ACCESIBLE; B) A CONTINUACION EN UN VALOR DE PH DE 2,0 A 7,0 Y UNA TEMPERATURA DE 50 A 90 (GRADOS) C SE VUELVE A CONDENSAR HASTA QUE LA VISCOSIDAD DE LA SOLUCION ES DE 4 A 1000 MM (AL CUADRADO) /S A 80 (GRADOS) C; Y C) DESPUES EL PRODUCTO DE CONDENSACION SE SOMETE A UN RANGO ALCALINO FUERTE A UN PH > O = 11,0 A ALTAS TEMPERATURAS. DE ESTA FORMA LOS PRODUCTOS DE CONDENSACION OBTENIDOS PRESENTAN UN CONTENIDO EN FORMALDEHIDO < 0,1% Y NECESITAN UNA ESTABILIDAD LARGA CARACTERISTICA ASI COMO UNAS PROPIEDADES DE LICUACION TAMBIEN A UN ALTO CONTENIDO EN MATERIA SOLIDA.
