Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a process for preparing 3-aminomethyl-3,5,5-trimethylcyclohexanol (IPAA) by hydrogenation of isophoronenitrile (IPN) with hydrogen over a catalyst.SOLUTION: A catalyst according to the invention comprises catalytically active metal foam bodies. The catalyst has as low a bulk density as possible while having a high activity for a specified hydrogenation reaction.SELECTED DRAWING: None 【課題】３−アミノメチル−３，５，５−トリメチルシクロヘキサノール（ＩＰＡＡ）を、触媒上での水素を用いるイソホロンニトリル（ＩＰＮ）の水素化によって、製造する方法。【解決手段】本発明による触媒は、触媒活性な金属フォーム体からなり、一方ではできるだけ小さいかさ密度を有し、かつ他方では、挙げた水素化反応の高い活性を有する。【選択図】なし
