| titleOfInvention | Tanning agent and curing agent based on dialdehydes |
| abstract | The invention relates to a tanning agent that is produced by reacting at least one aldehyde of general formula (I) with at least another identical or different aldehyde of formula (I), wherein the variables are defined as follows: Z is a single chemical bond, an optionally substituted C1-C12-alkyl, an optionally substituted C5-C12-cycloalkyl or an optionally substituted C6-C14-aryl, wherein the reaction is carried out in the presence of an acid catalyst and optionally in the presence of at least another carbonyl compound of formula (II), R1 to R4 represent, independent of one another, hydrogen, optionally substituted C1-C12-alkyl, optionally substituted C3-C12-cycloalkyl, optionally substituted C7-C13-aralkyl or optionally substituted C6-C14-aryl, provided that at least another aldehyde of formula (I) in which the radical of Z contains α hydrogen atoms or at least another carbonyl compound of formula (I) is present when Z is a single chemical bond or a radical without any hydrogen atoms. The invention also relates to a method for the production of said tanning agent, to the utilization thereof as curing agent, particularly for pretannage, tannage or retannage of animal skins using the inventive tanning agents. The invention further relates to a powder active agent containing one or more of said inventive tanning agents, to a method for the production of said powder active agents and to the use thereof as curing agent and to leather produced using the inventive tanning agents or the inventive method. |
