METHOD FOR PRODUCING OXIME

摘要

PURPOSE: A manufacturing method of oxime is provided to make the reuse of by-products possible by converting the by-product to cumene, and to make recirculation of the cumene possible to generate cumene hydroperoxide to be used in an ammoxidation step. CONSTITUTION: A manufacturing method of oxime comprises: a step of generating cumene hydroperoxide by oxidizing cumene; a step of generating a reaction mixture containing an oxime compound corresponding with ketone and 2-phenyl-2-propanol by ammoxidation of cumene hydroperoxide with ammonia and ketone under the presence of a catalyst; a step of separating an oxime compound and the 2-penyl-2-propanol to cumene; a step of recirculating a part of the cumene to the first step.
