sentences:  Oxo alcohol
  
  Oxo alcohols are alcohols that are prepared by adding carbon monoxide (CO) and hydrogen (usually combined together as synthesis gas) 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 (the aldol condensation reaction) can precede the hydrogenation.
