        Yield of liquid hydrocarbons is as high as 43.3% based on the C₂H₂, which reacts.  The liquid products contain some oxygenated compounds and some evidence exists indicating that they are alcohols.  The CO₂ reacts almost quantitatively with the CaO formed from the carbide and water vapor but not with that contained in the original carbide as an impurity.
