Yield:-

Reaction Conditions:

with hydrogen in 1,4-dioxane at 20 - 140; under 7500.75 - 60006 Torr; for 4 h;Autoclave;

Steps:

53 Example 51
General procedure: A stirrer chip, 300 mg of the catalyst (ReOX-Au / CeO2) obtained in Production Example 21 weighed, 4 g of 1,4-dioxane, and 500 mg of glycerin were placed in a glass inner cylinder for autoclave.The inner cylinder for the autoclave was placed in a 190 mL autoclave (high-pressure batch reactor) and covered.Next, the operation of filling 1 MPa of hydrogen into the autoclave and then exhausting the gas was repeated three times to expel the air inside the autoclave. The autoclave was filled so as to exhibit 8 MPa at 140 ° C. and 5 MPa at room temperature.Subsequently, the autoclave is set in a magnetic stirrer additional heating device, heated so that the temperature inside the reactor (inside the autoclave) becomes 140 ° C., and the reaction temperature is maintained at 140 ° C. for 32 hours at 250 rpm (Reaction time). = 32h) Stirred.Then, the mixture was cooled to room temperature, the hydrogen inside the autoclave was released, and the pressure was released.The analysis of the solution after the reaction was carried out in the same manner as in Example 1.From this, the conversion rate of glycerin and the selectivity of the product were calculated. The analysis results are shown in Table 9.
