Oxo alcohol

Oxo alcohols are alcohols that are prepared by adding carbon monoxide (CO) and hydrogen to an olefin to obtain an aldehyde using the hydroformylation reaction and then hydrogenating the aldehyde to obtain the alcohol. An intermediate step of adding two aldehydes together to obtain a larger aldehyde can precede the hydrogenation. Long chain oxo-alcohols are often prepared using alpha-olefins from the Shell higher olefin process, to give secondary alcohols such as isodecyl alcohol.
