Abstract
La presente invención se refiere a procedimiento para el curtido al cromo de pieles en tripa piqueladas con un producto de reacción constituído a partir de un sulfato básico de cromo (III) y ácidos dicarboxílicos alifáticos con 4 a 6 átomos de carbono y/o sus sales, caracterizado porque el producto de la reacción se prepara en solución acuosa a partir de el sulfato básico de cromo (III) y de 0,2 a 0,8 moles de los ácidos dicarboxílicos alifáticos por mol de óxido de cromo del sulfato básico de cromo y a continuación se ajusta la basicidad teórica a 0 hasta 50 por ciento con los álcalis usuales, verficándose la adición de el producto de la reacción al baño de piquelado en forma de solución acuosa con un contenido en óxido de cromo de al menos 5 por ciento o bien en forma pulverulenta en una cantidad de 0,9 hasta 1,5 por ciento de óxido de cromo (referido al peso de la piel en tripa), porque el volumen de el baño asciende a una cantidad inferior al 100 por ciento (referido al peso de piel en tripa), ascendiendo el valor final del pH a un valor superior a 4,0 y siendo la temperatura final superior a 40 grados C.
