Carbonaceous catalysts were characterized by TG-DTA,\u00a0<sup>13<\/sup>C MAS NMR, FT-IR, XRD, Raman, TPD and elemental analyzer. The production of 5-HMF was successfully demonstrated by the dehydration of fructose and glucose using lignin-derived solid acid catalyst in DMSO-[BMIM][Cl] (dimethyl sulfoxide and 1-butyl-3-methylimidazolium chloride) mixtures. It was found that lignin-derived solid acid catalyst (LCC) was the most active one in the dehydration of sugars. LCC coupled with microwave irradiation was used for the 5-HMF production, 84% 5-HMF yield with 98% fructose conversion rate was achieved at110 \u00b0C for 10 min. Furthermore, 99% glucose was converted with 68% 5-HMF yield under severer condition (160 \u00b0C for 50 min). LCC was recycled for five times, 5-HMF yield declined only 7%. It is concluded that LCC is an ideal catalyst for 5-HMF production, microwave and DMSO-[BMIM][Cl] can effectively promote the dehydration.<\/span><\/p>\n<p><span style=\"color: #003300\">\u00a0 This work entitled \u201cConversion of fructose and glucose into 5-hydroxymethylfurfural with lignin-derived carbonaceous catalyst under microwave irradiation in dimethyl sulfoxide-ionic liquid mixtures\u201d authored by\u00a0<strong>Feng Guo and Zhen FANG\u00a0<\/strong>was published online in Bioresource Technology:\u00a0<a href=\"http:\/\/dx.doi.org\/10.1016\/j.biortech.2012.02.108\" target=\"doilink\"><span style=\"color: #003300\">http:\/\/dx.doi.org\/10.1016\/j.biortech.2012.02.108<\/span><\/a><strong><\/strong><\/span><\/p>\n<p><span style=\"color: #003300\">\u00a0<\/span><\/p>\n<p><span style=\"color: #003300\">\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Renewable biomass is an ideal alternative for fossil re [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"_links":{"self":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/1989"}],"collection":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/comments?post=1989"}],"version-history":[{"count":0,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/posts\/1989\/revisions"}],"wp:attachment":[{"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/media?parent=1989"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/categories?post=1989"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/woodrefinery.com\/zhenfang\/wp-json\/wp\/v2\/tags?post=1989"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
