<P>PROBLEM TO BE SOLVED: To provide a method capable of providing useful products, e.g. an aldehyde, an alcohol and its formic acid ester by reacting an olefin or an olefin mixture in higher yield by a conventional method. <P>SOLUTION: In the hydroformylation having one or more steps in which an unmodified cobalt complex acts as a catalyst in at least reactor, an aldehyde (a hydroformylation product) in an amount of 0.5-20 mol% based on an olefin fed is introduced into the reactor. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
