Abstract
Cellulose and even spruce can be converted efficiently into valuable platform chemicals via combined hydrolysis and hydrogenation in the aqueous phase. Thereby, heteropoly acids together with supported ruthenium catalysts show not only high activity but also remarkable selectivity to sugar alcohols reaching up to 81% yield of C(4) to C(6) sugar alcohols in only 7 h at 160 °C.
摘要
纤维素甚至云杉都可以通过在水相中的联合水解和加氢反应有效地转化为有价值的平台化学品。在此过程中，杂多酸与负载型钌催化剂不仅表现出很高的活性，而且对糖醇具有显著的选择性，在 160°C 仅 7 小时内 C(4)到 C(6)糖醇的收率高达 81%。
