Leather tanning process using aluminium (III) and titanium (IV) complexes |
| abstract |
In a leather tanning process, animal skins are treated with a tanning agent comprising an aluminium (III)/titanium (IV) mixed complex with a salt of a polyhydroxymonocarboxylic acid as a masking compound. The masking compound preferably has the general formula: HOCH2(CHOH)n CO2M wherein M is an alkali metal, and n is 2 to 6. Especially preferred masking compounds are sodium gluconate and sodium glucoheptonate. The same process can be used for a wide range of skins, both as a base tannage and in combination with other tanning processes. |
