Abstract
This method for producing an unsaturated aldehyde is a method for producing an unsaturated aldehyde by partially oxidizing an alkene using a multi-tubular fixed-bed reactor, wherein Sh of the first-layer catalyst defined by formula (I) is 0.5 / hr or more in a reaction time (TOS) comprised between 500 hours and 55000 hours. Formula (I): Sh ( / hr) = (the specific surface area of the catalyst in TOS range comprised between 500 hours and 55000 hours - the specific surface area of the catalyst before the reaction) ÷ the specific surface area of the catalyst before the reaction × 1000000 ÷ the reaction time (hr)
