METHOD FOR THE PRODUCTION OF ISOPHORONDIAMINE (IPDA, 3-AMINOMETHYL-3,5,5-TRIMETHYLCYCLOHEXYLAMINE) |
| 摘要 |
The invention relates to a method for the production of 3-aminomethyl-3,5,5-trimethylcyclohexylamine (isophorondiamine, IPDA) with a cis/trans isomer ratio of at least 70/30 from 3-cyano-3,5,5-trimethylcyclohexanon (isophorone nitril, IPN), NH3 and H2, wherein hydrogenation is carried out in the presence of a hydrogenation catalyst at temperatures ranging from 50 to 200 DEG C and at a pressure ranging from 50 to 300 bar. The invention is characterized in that the alkali metal content of the hydrogenation catalyst is </= 0.03 percent by weight, calculated as alkali metal oxide and relative to the total weight of the catalyst. The alkali metal content also comprises the content of Li, Na, K, Rb and Cs, more particularly the content of Na. The invention further relates to methods for the production of hydrogenation catalysts having an alkali metal content (more particularly a sodium content) of </= 0.03 percent by weight, calculated as alkali metal oxide/sodium oxide and relative to the total weight of the catalysts. The invention also relates to the hydrogenation catalysts as such.
