METHOD FOR EVAPORATING CYCLOHEXANONE OXIME AND EVAPORATOR TO BE USED THEREFOR, AND METHOD FOR PRODUCING amp;epsi;-CAPROLACTAM AND PRODUCTION UNIT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method for evaporating cyclohexanone oxime so as to diminish byproduct formation, and to provide an evaporator to be used for the method.;SOLUTION: This method for evaporating cyclohexanone oxime comprises the following practice: a mixture of the cyclohexanone oxime and a diluent therefor is issued via an inlet tube 6 into a fluidized bed 11 where a granular inert matter having a heat capacity enough to feed a heat necessary for evaporating the mixture is fluidized by an inert gas.;COPYRIGHT: (C)2002,JPO
