        Utilization of the heat of reaction of carbide with H₂, CO₂, and H₂O for the cracking of fluid paraffin was studied.  In the synthesis of isobutanol from the mixture of CO and H₂ at 320° in the presence of carbide, the heat of reaction is found to be 179 kcal. per mol. of carbide.  Absorption of the heat of reaction takes place by cracking of fluid paraffin; the temperature of the reaction mixture remains uniform.
