Catalytic activity of HKUST-1 in the oxidation of trans-ferulic acid to vanillin

Abstract

HKUST-1 was used as a catalyst in the conversion, under mild oxidation conditions, of trans-ferulic acid to vanillin. When catalyst was activated under vacuum, the average reaction yield reached 95%.

One‐Pot, Clean Synthesis of Vanillic Acid from Ferulic Acid

“…Remarkably, the catalytic oxidation of trans ‐ferulic acid to vanillin with 95 % reaction yield in only 1 h over porous coordination polymer HKUST‐1 using H 2 O 2 as primary oxidant in EtOH/acetonitrile under reflux was recently reported …”

“…The catalytic nature of the reaction is confirmed by the unmodified crystalline structures of Bi 2 WO 6 before and after reaction, as shown by the XRD patterns in Figure . Like in photocatalytic reactions, the catalyst was truly recyclable, with the same catalyst sample filtered and re‐used in all catalytic tests (>10) under the optimal reaction conditions (1.5 g L −1 ), without any noticeable reduction in activity.…”

Sulfamic acid incorporated HKUST-1: a highly active catalyst and efficient adsorbent

“…The high chemical and thermal stability of many MOFs has made them adjustable to metal-complex functionalization and PSM, which extend their applications to water-containing processes and promote their efficiency in catalytic conversion. [5][6][7] The catalytic activity of varied MOFs has been demonstrated for reactions such as catalytic transformations, hydrogenation, polymerization, cyanosilylation, [8][9][10] as well as for isomerization and enantioselective separations. 11,12 Although sulfamic acid "SA" has strong Brønsted acidity, it has a relatively poor surface area which restricts its application as solid-acid catalysts.…”

HKUST-1-Supported Cerium Catalysts for CO Oxidation

“…HKUST-1 has already been used as a catalyst in a few reactions. For example, Yepez et al [20] tested it in the reaction of oxidation of trans-ferulic acid to vanillin. HKUST-1 was found to be a very efficient catalyst in this reaction, providing a 98% acid conversion.…”
