1872. TSUNEOKA, S., AND MURATA, Y. Synthesis of Benzine From Carbon Monoxide and Hydrogen at Ordinary Pressure. XXXVI. Relation of the Activity of the Catalyst to the Synthesis Requirements at Too High a Temperature. Jour. Soc. Chem. Ind. (Japan), vol. 40, No. 12, suppl., 1937, pp. 478-484; Sci. Papers Inst. Phys.

Influence of raising the optimum temperature of 195° to 300° has been studied. In the range 240°-250° no synthesis of benzine takes place; CH₄ and some H₂CO₃ are formed. At 270° benzine is again formed, but in small quantity. If the reaction is carried on at a temperature above the optimum and then brought back again to the optimum the catalyst loses its characteristic activity, depending on the amount of treatment at the high temperature. When the reaction has been carried on at a temperature higher than the optimum, any benzine subsequently formed at the optimum temperature will have a higher I number proportionate to the increase in temperature used in the previous treatment.
