Abstract

Aplicación de compuestos carbonílicos para proceso de curtido de cueros con utilización de alfa -hidroxi-cetonas de fórmula general(I) donde R puede ser un grupo alquilo lineal o ramificado o aun aromático y R1 y R2 pueden ser hidrógeno, alquilo lineal o ramificado o aun aromatico, o también compuestos beta hidroxicetónicos con fórmula general (II) donde R puede ser un grupo alquilo lineal o ramificado o aun aromático. Aplicación de compuestos carbonílicos al curtido en soluciones acuosas en concentraciones de 0,1 % hasta 100%,bajo la forma de mezclas con otros compuestos orgánicos diluyentes.Application of carbonyl compounds for leather tanning process using alpha-hydroxy ketones of general formula (I) where R can be a linear or branched or even aromatic alkyl group and R1 and R2 can be hydrogen, linear or branched alkyl or even aromatic, or also beta hydroxy ketone compounds with general formula (II) where R can be a linear or branched alkyl group or even aromatic. Application of carbonyl compounds to tanning in aqueous solutions in concentrations from 0.1% to 100%, in the form of mixtures with other organic diluent compounds.
