METHOD FOR PRODUCING ACRYLONITRILE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing acrylonitrile advantageous in aspects of equipment or variable cost when industrially carrying out the method in the method for producing the acrylonitrile by a vapor-phase catalytic oxidizing reaction of a hydrocarbon with ammonia. SOLUTION: This method for producing the acrylonitrile is characterized in that the ratio of acrolein formed as a by-product based on the acrylonitrile in an outlet gas of a reactor is <=500 wt.ppm.
