Abstract: 1. A METHOD FOR THE PREPARATION OF AN IMMOBILIZED ENZYME WHICH COMPRISES REACTING AN AQUEOUS SOLUTION OF AN EZYME WITH AN EPOXY CONTAINING POLYMER PREPARED BY THE REACTION OF A SOLID POLYMERIC DIGLYCIDYL ETHER OF BISPHENOL A HAVING AN AVERAGE OF AT LEAST ABOUT ONE REPEATING UNIT WITH A STOICHIOMETRIC EXCESS OF A NITRILE REACTANT SELECTED FROM ACRYLONITRILE AND METHACRYLONITRILE.

Abstract: A METHOD FOR CONVERTING A KETOXIME TO AN N-SUBSTITUTED AMIDE BY REACTING A KETOXIME WITH A COMPLEX OF AN NSUBSTITUTED CARBOXYLIC ACID AMIDE AND SULFUR TRIOXIDE TO FORM A NOVEL COMPOUND OF THE KETOXIME, CARBOXYLIC ACID AMIDE AND SULFUR TRIOXIDE AND DECOMPOSING THIS COMPOUND TO PRODUCE AN N-SUBSTITUTED AMIDE CORRESPONDING TO THE KETOXIME. CYCLOHEXANONE OXIME IS CONVERTED TO CAPROLACTAM.
