        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.
