Reaction Conditions:
with palladium on activated charcoal;hydrogen at 20 - 110; under 14997.7 Torr;Pressure;Temperature;
Steps:
1 Example 1
30.0 g of 2-ethyl-2-hexenal was placed into a 100 ml pressure reaction tank equipped with a gas-introducing mixer to form a reaction liquid. Then a specific Pd/C (palladium on carbon) catalyst for hydrogenation, whose carrier impurity have a modified compositions with a surface area of 1,000 m2/g as shown in Table 1, was added.10067] Hydrogen gas was introduced to 290 lb/in2 where the pressure was maintained. The reaction tank was started with its stirring shaft rotating at 1,000 rpm. Stirring was performed at room temperature and consistent pressure for 10 minutes and then the reaction liquid was heated to 110° C. for reaction for 4-7 hours.10068] Upon completion of the reaction, the hydrogen gas was cut oil and the hydrogen gas inside the reaction tank was exhausted. The reaction liquid was cooled to the room temperature. Afier having the catalyst filtered out, the reaction product was analyzed.10069] The results are shown in Table 1, when the Pd/C catalyst was used in the amount of 0.022 g, the yield of 2-ethylhexanal was 99.45%.
