The physicochemical and thermal properties of GL are expected to be controllable by varying the glycol type. In this study, caprylyl glycol (CG), which is a biobased glycol derived from the caprylic acid component of coconut and palm oils, was used to investigate the effects on the acid-catalyzed solvolysis of softwood. The reactions were performed at 140, 150, and 160 \u00b0C for 30\u2013120 min to obtain lignin derivatives (CG-lignin: CGL). The chemical and physical properties of CGLs were investigated. Two-dimensional heteronuclear single-quantum coherence nuclear magnetic resonance analysis suggested that CGL possesses an \u03b1-CG-\u03b2-O-4 structure as CG is grafted onto the lignin structure. CGLs prepared at higher reaction temperatures exhibited lower molecular weights. The thermomechanical analysis of CGL revealed a glass transition temperature of 89\u201396 \u00b0C and a viscous thermal flow temperature of 134\u2013155 \u00b0C.<\/jats:p>","DOI":"10.1021\/acsomega.4c03278","type":"journal-article","created":{"date-parts":[[2024,6,10]],"date-time":"2024-06-10T20:33:50Z","timestamp":1718051630000},"page":"27610-27617","source":"Crossref","is-referenced-by-count":2,"title":["Acid-Catalyzed\nSolvolysis of Softwood in Caprylyl\nGlycol to Produce Lignin Derivatives"],"prefix":"10.1021","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-7714-8933","authenticated-orcid":true,"given":"Tomohiro","family":"Yamada","sequence":"first","affiliation":[{"name":"University of Tsukuba , , 1-1-1 Tennodai , , ,","place":["Tsukuba, Ibaraki, Japan, 305-8577"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7578-7392","authenticated-orcid":true,"given":"Yuki","family":"Tobimatsu","sequence":"additional","affiliation":[{"name":"Kyoto University , , Gokasho , , ,","place":["Uji, Kyoto, Japan, 611-0011"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7201-0222","authenticated-orcid":true,"given":"Thi Thi","family":"Nge","sequence":"additional","affiliation":[{"name":"Forestry and Forest Products Research Institute , , 1 Matsunosato , , ,","place":["Tsukuba, Ibaraki, Japan, 305-8687"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8028-4896","authenticated-orcid":true,"given":"Yusuke","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Forestry and Forest Products Research Institute , , 1 Matsunosato , , ,","place":["Tsukuba, Ibaraki, Japan, 305-8687"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0585-2192","authenticated-orcid":true,"given":"Tatsuhiko","family":"Yamada","sequence":"additional","affiliation":[{"name":"University of Tsukuba , , 1-1-1 Tennodai , , ,","place":["Tsukuba, Ibaraki, Japan, 305-8577"]},{"name":"Forestry and Forest Products Research Institute , , 1 Matsunosato , , ,","place":["Tsukuba, Ibaraki, Japan, 305-8687"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2024,6,10]]},"reference":[{"key":"2026081708352215000_cit1","doi-asserted-by":"publisher","first-page":"112732","DOI":"10.1016\/j.indcrop.2020.112732","article-title":"Technical lignin and its potential modification routes:\nA mini-review","volume":"154","author":"Kazzaz","year":"2020","journal-title":"Ind.
