Abstract

Process for the preparation of a new agent for the tanning of skins, especially suitable for the partial replacement of the chromium in the classic operations of tanning, characterized in that in its realization it comprises dissolving, or attacking until its complete dissolution a salt or an aluminum hydroxide, in a hydrochloric and/or sulfuric acid medium, treat the concentrated solution obtained above with a complexing agent selected from polycarboxylic acids or their alkali salts, and bring it to ph between 3.9 and 4.3 by treatment with an alkalizing agent, and, eventually convert the product into a solid material by removing water.
