An autoclave made of stainless steel, equipped with a rotary stirrer and having a capacity of 300 ml. was charged with 50 ml. of isobutanol, 50 ml. of diisobutyl adipate as a solvent, 1 g. of palladium-on-activated-carbon (2 wt.%Pd) and 4 mg. of lithium chloride ##EQU2## After sealing and heating the reaction system to 105° C., the reaction was carried out at the same temperature for one hour, passing a gas mixture consisting of 78 vol.% of ethylene, 18 vol.% of carbon monoxide and 4 vol.% of oxygen; maintaining the total pressure at 30 atm.; and supplying isobutyl nitrite continuously at a rate of 39 mmol./hr. After completion of the reaction, the reaction mixture was analyzed quantitatively by gas chromatography. As the result, it was revealed that 20.4 mmol. of diisobutyl succinate was produced and only 1.1 mmol. of diisobutyl oxalate was produced as by-product.
