The application of carbonyl compounds in the process of tanning hides, including the use of selected alpha-hydroxy ketones that present a general formula as (I) where R may be a linear or ramified alkyl group or even aromatic group and R1 and R2 may be hydrogen, linear or ramified alkyl or even aromatic, as, for example, R1=R2=H and R=CH2CH3 or, preferentially, R1=R2=H and R=-CH3, or still, the use of selected beta-hydroxyl ketones presenting a general formula s (II) where R may be a linear or ramified alkyl group or even aromatic group as, for example, R, R1 and R2=-CH3 and R3=H, preferentially R, R2 and R3=-CH3, and R1=H. The application of carbonyl compounds in the process of tanning hides, with the possibility of using a water solution, in concentrations that may vary from 0.1% till its pure state, that is, 100%, or still, in mixtures with other organic compounds acting as dilutents. |
