Biomass‐derived di‐ethers, 2,5‐bis(alkoxymethyl)furans (BAMFs), are currently envisaged as promising biodiesel or additives. Herein, Zr‐SBA prepared by a urea hydrolysis method (Zr‐SBA‐UH) is used as a highly active bifunctional catalyst for the reductive etherification of 5‐hydroxymethylfurfural (HMF), and offers the 2,5‐bis(isopropoxymethyl)furan (BPMF) yield up to 93.6% using isopropanol as the solvent and hydrogen source. Zirconia is proved to be located mainly out of the mesoporous channels for Zr‐SBA‐UH, which leads to significant enhancement in the acid content of the catalyst, and then greatly promotes the catalytic performance of Zr‐SBA‐UH for the reductive etherification of HMF. The general soundness of Zr‐SBA‐UH in other monohydric alcohols is further confirmed in this contribution, guaranteeing that a family of BAMFs can be prepared by this catalytic system. In addition, Zr‐SBA‐UH is a robust catalyst that can be reused for at least five continuous runs without a significant loss of its catalytic activity.

Zr-SBA催化剂上5-羟基甲基糠醛作为生物柴油组分的高效还原醚化为2,5-双（烷氧基甲基）呋喃

目前设想将生物质衍生的二醚2,5-双（烷氧基甲基）呋喃（BAMF）作为有前途的生物柴油或添加剂。本文中，通过尿素水解法（Zr-SBA-UH）制备的Zr-SBA被用作高活性双功能催化剂，用于5-羟甲基糠醛（HMF）的还原醚化，并提供2,5-双（异丙氧基甲基）呋喃使用异丙醇作为溶剂和氢源，（BPMF）收率可达93.6％。事实证明，氧化锆主要位于Zr-SBA-UH的介孔通道之外，这会大大提高催化剂的酸含量，然后大大提高Zr-SBA-UH的还原性醚化催化性能。 HMF。此贡献进一步证实了Zr‐SBA‐UH在其他一元醇中的总体安全性，确保该催化体系可以制备一系列BAMF。另外，Zr-SBA-UH是一种坚固的催化剂，可以重复使用至少五次，而不会显着降低其催化活性。
