The efficient etherification of 2,5-bis(hydroxymethyl)furan (BHMF) to 2,5-bis(propoxymethyl)furan (BPMF) was achieved by using low-cost amorphous silica-aluminas (ASA) catalysts in a fixed-bed reactor. A considerable yield of BPMF up to 85.1 % was obtained over ASA-30 catalyst under the reaction conditions of 140 °C, 2.0 MPa of N , and 0.015 h of WHSV. The excellent performance of ASA-30 catalyst could be attributed to the relatively stronger acidity (>375 °C) and larger mesoporous size (6 nm), thereby facilitating the conversion of BHMF to BPMF. In addition, the lower ratio of Brønsted/Lewis acid sites for ASA catalyst was found to efficiently suppress the occurrence of side reactions.
在固定床反应器中使用低成本的无定形硅铝酸盐（ASA）催化剂实现了2,5-双（羟甲基）呋喃（BHMF）向2,5-双（丙氧基甲基）呋喃（BPMF）的高效醚化反应。在140 °C、2.0 MPa氮气和0.015 h的重量时空速反应条件下，使用ASA-30催化剂可获得高达85.1 %的可观BPMF产率。ASA-30催化剂的优异性能可归因于相对较强的酸度（>375 °C）和较大的中孔尺寸（6 nm），从而促进了BHMF向BPMF的转化。此外，发现ASA催化剂较低的布朗斯特/路易斯酸位比例可有效抑制副反应的发生。
