Reaction Conditions:

with hydrogen in hexane at 140; under 15001.5 - 60006 Torr; for 7 h;Inert atmosphere;Autoclave;

Steps:

5 Example 5

To a volume of 50 mL of Hastelloy autoclave was placed 10 mL of solvent n-hexane,1 mmol each of the reaction substrates shown in Table 2(The reaction of each reaction substrate were followed by experimental operation)The Au / Al2O3 catalyst prepared in Example 2 was prepared(The theoretical load of gold 1%)(Containing 5μmol),The autoclave was sealed and the inside of the autoclave was replaced with nitrogen three times,And then into the 2MPa of CO2 gas and 6MPa of H2,Keep the kettle gas pressure is 8MPa,Placed on the chassis with aluminum block on the magnetic stirrer,So that the temperature quickly rose to 140 ,Open the magnetic stirring,Stirring at 1000 rpm for 7 hours,After cooling, add a certain amount of n-octane as the internal standard,Using gas chromatography (FID detector),The results are shown in Table 2.
