METHOD OF CONVERSION OF KETOXIME OR ALDOXIME TO THE CORRESPONDING AMIDE Russian patent published in 1998 - IPC

Abstract RU 2101278 C1

FIELD: chemical technology. SUBSTANCE: amide is obtained by Beckman rearrangement in sulfoxide solution, preferably, in dimethylsulfoxide using heterogeneous strong acid catalyst containing a carrier with the sulfonated benzene rings that have one or more electron-accepting groups also. Other substituents are C₁-C₅-alkyl or arylalkyl. Nitro-group, halogen or sulfoacid group can be used as an electron-accepting group. Cyclic C₆-C₁₂-ketoxime is used as an oxime. Sulfonated polysryrenedivinylbenzene resin is used as a carrier in catalyst. EFFECT: improved method of conversion. 12 cl, 1 tbl
