ABSTRACT:
To provide a process capable of producing an aldehyde with a 2-position branched long-chain alkyl with high yield and high selectivity. The process for producing an aldehyde with a 2-position branched long-chain alkyl represented by the following general formula (2) contains: using a 2-position branched epoxide represented by the following general formula (1) as a raw material; and subjecting the epoxide to acid rearrangement reaction with a polyacid of a metallic oxoacid as a catalyst. In the formulae, n represents an integer of from 5 to 17.
