(1)独自触媒の開発(大阪大学)
1 グリセロールから1,3-プロパンジオール(1,3-PD)の高選択的合成触媒の開発
グリセロールの有用物質への変換方法は、酸化法を始め多岐にわたるが、目的生成物をアルコールとした場合には、水素化分解法が最も有効な方法としてあげられる。
英文要約Glycerol is one of the most abundant and cheap biomass feedstock obtained from oleo industry. Recently, production of glycerol is rapidly increased due to the demand of biodiesel production in the world. Therefore, the development of new catalytic processes to convert glycerol to value-added chemicals or fuel such as 1,2- or 1,3-propanediol, acrolein, polyglycerol, and syngas, is undoubtedly a promising development in the future bio refinery. One of the promising approaches is the hydrogenolysis of glycerol, leading to 1,3-propandiol. 1,3- propanediol has a wide range of practical applications, like its polymerization to polyesters and polyurethanes.
Currently, the commercial production of 1,3- propanediol is mainly through the route of fermentation of sugar and hydroformylation of ethylene oxide or acrolein. Direct synthesis of 1,3- propanediol by glycerol hydrogenolysis represents a sustainable process with valuable potential applications.
In our research in this program, Pt-Metal-W catalysts showed very high performance on the formation of 1,3- propanediol under mild reaction conditions. On the reaction of glycerol hydrogenolysis by liquid-phase-reactions, the Pt-Al-W catalyst gave high conversion (>84%) and yield (35%) of 1,3-propanediol. Also, Ir-Re/SiO2 catalyst also gave high conversion (>71%) and yields (30%) of 1,3-propanediol. The activities of these catalysts were maintained for over 100Hrs by continuous reactions.
We also examined 1,2-propandiol synthesis by glycerol hydrogenolysis using Cu-Al-hydrotalcite catalyst, which was developed last year, and we could get very high conversion (98%) and high yield (97%) of 1,2-propanediol. This high activity was maintained continuously 100Hrs.
We will continue the research on the glycerol hydrogenolysis to 1,3- and 1,2-propandiols. The liquid-phase reaction methods will be investigated.
