Description
The use of pressurized oxygen greatly enhanced catalytic activity for oxidative esterification of propionaldehyde to methyl propionate with methanol using heavy-metal-free Pd/C and Pd/Al2O3. For example, the conversion of propionaldehyde, the selectivity to methyl propionate, and the yield of the propionate using 5 % Pd/Al2O3 were 99.9, 62.7, and 62.6 %, respectively, at 1.5 MPa of oxygen gas and 333 K. This result demonstrated that Pb doping of Pd catalysts was not needed to achieve comparable activity, which runs contrary to previous reports, in which it had been suggested that loading of Pd catalysts using a heavy metal such as Pb was needed for the great activity such as 93.2, 76.8, and 71.6 % of the conversion of propionaldehyde, the selectivity to methyl propionate, and the yield of the propionate, respectively, at 0.3 MPa of oxygen gas and 353 K using 5 % Pd/Al2O3 doped with 5 % Pb.
Description Alternative
プロピオンアルデヒドからプロピオン酸メチルへの酸化的エステル化は,鉛などの重金属で修飾した活性炭担持もしくはアルミナ担持パラジウム触媒で行うと良好に進む,と従来報告されていた。たとえば,5 % の鉛で修飾した5 % Pd/Al2O3 触媒を用いると, 酸素加圧0.3 MPa, 反応温度353 K において,93.2 % のプロピオンアルデヒド変化率,76.8 % のプロピオン酸メチルの選択率が報告されていた。しかし,酸素加圧下(1.5 MPa),重金属で修飾していない5 % Pd/C を用いて反応温度333 K で本反応を行うと,99.9 % のプロピオンアルデヒド変化率において,62.7 % のプロピオン酸メチル選択率という従来の報告に匹敵する活性が得られ,鉛などの重金属で修飾したパラジウム触媒を用いる必要がないことが明らかになった。
