Considerable progress has been made recently in the catalytic conversion of renewable biomass resources to methyl lactate (MLA). However, conceiving eco‐friendly and effective catalytic systems for the production of MLA from biomass carbohydrates remains a key challenge. Herein, we report a multifunctional catalyst Sn(salen)/IL, consisting of a Sn(salen) complex and an imidazolium‐based ionic liquid (IL), which acts via an intramolecular synergistic effect to convert carbohydrates to MLA in methanol. The versatile properties of the resultant catalyst were revealed to be responsible for the conversion of fructose to MLA and the efficient suppression of undesired side reactions. This catalyst displayed outstanding catalytic activity, high selectivity, and excellent recyclability, giving an MLA yield of up to 68.9 % at 160 °C after 2 h. The results of this study will contribute to new approaches for designing synergistic catalysts for producing liquid fuels and chemicals from biomass resources.

使用离子液体功能化的含锡催化剂从碳水化合物协同生产乳酸甲酯

最近，在将可再生生物质资源催化转化为乳酸甲酯（MLA）方面取得了可观的进展。然而，构想从生物质碳水化合物生产MLA的生态友好和有效的催化系统仍然是一个关键的挑战。本文中，我们报道了一种多功能催化剂Sn（salen）/ IL，由Sn（salen）配合物和咪唑基离子液体（IL）组成，其通过分子内协同作用将甲醇中的碳水化合物转化为MLA。结果表明，所得催化剂的多用途性质是果糖向MLA转化以及有效抑制不良副反应的原因。该催化剂显示出出色的催化活性，高选择性和出色的可回收性，在2 h后在160°C时MLA收率高达68.9％。
