The products obtained through microwave heating and oil\u2010bath heating with the same reaction vessel and temperature profile are quantitatively compared. Dimer degradation is found to proceed through consecutive elementary reactions. The phenolic dimer is dehydroxylated and this is followed by the spontaneous cleavage of C<jats:sub>\u03b1<\/jats:sub>\u2212C<jats:sub>\u03b2<\/jats:sub> and C\u2212O\u2212C bonds to produce guaiacol, vanillin, and vanillic acid. The reaction of the nonphenolic dimer produces veratric acid, veratraldehyde, and guaiacol. Microwave irradiation accelerates cleavage of the side chain and the oxidation of vanillin to vanillic acid. However, no acceleration of veratraldehyde oxidation to veratric acid or aromatic ring cleavage to produce dicarboxylic acids is observed. The selective acceleration of elementary reactions during the degradation of model lignin compounds indicates that microwaves interact with reaction intermediates that are sensitive to electromagnetic waves.<\/jats:p>","DOI":"10.1002\/cssc.202000502","type":"journal-article","created":{"date-parts":[[2020,4,10]],"date-time":"2020-04-10T08:20:25Z","timestamp":1586506825000},"page":"4510-4518","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Directly Microwave\u2010Accelerated Cleavage of C\u2212C and C\u2212O Bonds of Lignin by Copper Oxide and H<sub>2<\/sub>O<sub>2<\/sub>"],"prefix":"10.1002","volume":"13","author":[{"given":"Chen","family":"Qu","sequence":"first","affiliation":[{"name":"Laboratory of Biomass Conversion Research Institute for Sustainable Humanosphere Kyoto University  Gokasho Kyoto 611-0011 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keigo","family":"Ito","sequence":"additional","affiliation":[{"name":"Laboratory of Biomass Conversion Research Institute for Sustainable Humanosphere Kyoto University  Gokasho Kyoto 611-0011 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isamu","family":"Katsuyama","sequence":"additional","affiliation":[{"name":"Laboratory of Biomass Conversion Research Institute for Sustainable Humanosphere Kyoto University  Gokasho Kyoto 611-0011 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiko","family":"Mitani","sequence":"additional","affiliation":[{"name":"Laboratory of Applied Radio Engineering for Humanosphere Research Institute for Sustainable Humanosphere Kyoto University  Gokasho Uji Kyoto 611-0011 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiichiro","family":"Kashimura","sequence":"additional","affiliation":[{"name":"Information Technology Section General Education Division College of Engineering Chubu University  1200 Matsumoto-cho Kasugai Aichi 487-8501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0220-4157","authenticated-orcid":false,"given":"Takashi","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Laboratory of Biomass Conversion Research Institute for Sustainable Humanosphere Kyoto University  Gokasho Kyoto 611-0011 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,5,15]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1246843"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-28418-2_12"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0040-4039(00)83996-9"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/b803001b"},{"key":"e_1_2_7_5_1","first-page":"66","volume-title":"Production of Biofuels and Chemicals with Microwave","author":"Li H.","year":"2015"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fuproc.2015.12.019"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1872-5813(14)60030-X"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fuproc.2017.03.020"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5RA26235F"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/ef402062w"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.energyfuels.5b00735"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/cssc.201601795"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/acssuschemeng.7b02883"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200400655"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200400655"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1627\/jpi.61.121"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/ie400719v"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.3891\/acta.chem.scand.31b-0561"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00383453"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1515\/hfsg.1982.36.1.43"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00350807"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00350692"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1005620521240"},{"key":"e_1_2_7_23_1","first-page":"655","volume":"11","author":"Tarabanko V.
