Abstract

Procedure for obtaining high concentration tanning formulations, based on glutardialdehyde derivatives as an active component, characterized in that a 2-alkoxy-3,4-dihydro-2H-pyran is reacted in the presence of an acid with an alcohol aliphatic, inferior, mono or polyvalent in a single step and the reaction solution obtained is then reacted with formaldehyde in the presence of a base.
