Reaction Conditions:
with hydrogen in dodecane at 200; under 37503.8 Torr; for 8 h;Temperature;Pressure;
Steps:
4 Active metal Ru modified MeaXbAlc composite catalyst catalyzes the hydrodeoxygenation of fatty acid (ester) to prepare fatty alcohol
General procedure: In a 25 mL reactor,50 mg of oleic acid and 5 mg of each of the 0.3% Ru/MeaXbAlc composite catalysts prepared in Preparation Example 6 shown in Table 1 were added (before use,These composite catalysts were pre-reduced in a closed reactor under a hydrogen atmosphere at room temperature for 3 h)Then add 10 mL of n-hexane,Under a hydrogen atmosphere of 2 MPa,Heated to 200 ° C and under magnetic stirring conditions,Reaction 8h. After the reaction is completed, it is cooled to room temperature.After the exhaust gas is vented, the reaction solution is diluted with n-hexane.Separating the catalyst solids by centrifugation,Thus, a reaction liquid was obtained, and the obtained reaction liquid was subjected to gas chromatography analysis.Gas chromatographic conditions were: GC99 gas chromatography, FID detector, capillary column (HP-5 30m ×0.320mm × 0.25μm), programmed temperature, the initial temperature of the oven is 100 ° C, and the temperature is raised to 160 ° C at a heating rate of 5 ° C / min, and kept3 minutes. The carrier gas was 99.99% high purity nitrogen at a flow rate of 1 mL/min.
