CONJUGATED DIENE PRODUCTION METHOD |
摘要 |
Disclosed is a method for producing a conjugated diene by subjecting a monoolefin having a carbon atom number of 4 or more and an oxygen gas to an oxidative dehydrogenation reaction by using a molybdenum-containing metal oxide catalyst under heat removal with a coolant, wherein an amount of molybdenum adhered onto a cooling heat transfer surface within a reactor is kept at not more than 20 mg/m2, or not only a surface roughness Ra of a cooling heat transfer surface within a reactor is not more than 3 μm, but a temperature difference between a reaction temperature and a coolant temperature is in the range of from 5 to 220° C. |
