VERFAHREN ZUR UMWANDLUNG VON OXIMEN ZU AMIDEN

The invention relates to a process for the conversion of a ketoxime or an aldoxime into a corresponding amide in which a solution of the oxime in a solvent is contacted with a heterogeneous, strongly acidic catalyst, the heterogeneous catalyst being a carrier with sulphonated benzene rings and the s...

Zusammenfassung:	The invention relates to a process for the conversion of a ketoxime or an aldoxime into a corresponding amide in which a solution of the oxime in a solvent is contacted with a heterogeneous, strongly acidic catalyst, the heterogeneous catalyst being a carrier with sulphonated benzene rings and the sulphonated benzene rings also carrying an electron-withdrawing group. The invention relates in particular to the conversion of cyclohexanone oxime into the corresponding epsilon -caprolactam.
