More than 60% of non-condensed units were rapidly converted to diphenylmethane type units at early stage of the treatment with concentrated sulfuric acid. After that, further\ncondensation of lignin scarcely occurred. The formation ratio of diphenylmethane type to other type\ncondensed units was about three during the treatment with concentrated sulfuric acid. The modification of\nlignin during heating of wood began above 120℃ and was mainly diphenylmethane type condensation.\nAbout 40 and 75% of non-condensed units were convered to diphenylmethane type units by heating dry and\nwet wood meals at 220℃, respectively. The conversion rate to diphenylmethane type units doubled by\nincreasing the temperature from 180 to 220℃ and by the presence of water.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Faculty of Bioresources, Mie University"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0471","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10073846","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"657","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"木材の加熱および硫酸処理過程におけるリグニンの縮合反応"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Funaoka, Masamitsu","creatorNameLang":"en"},{"creatorName":"船岡, 正光","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kako, Tatsunari","creatorNameLang":"en"},{"creatorName":"加古, 辰成","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubomura, Makoto","creatorNameLang":"en"},{"creatorName":"久保村, 実","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN100738460000604.pdf","filesize":[{"value":"418.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN100738460000604.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5724/files/AN100738460000604.pdf"},"version_id":"60b958ea-71a2-4925-b074-a9e1661bc532"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Acid hydrolysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Heating","subitem_subject_scheme":"Other"},{"subitem_subject":"Lignin condensation","subitem_subject_scheme":"Other"},{"subitem_subject":"Dipheylmethane","subitem_subject_scheme":"Other"},{"subitem_subject":"Nucleus exchange reaction","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Occurrence of Diphenylmethane Type Condensation in Lignin during Heating and Sulfuric Acid Treatment of Wood","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Occurrence of Diphenylmethane Type Condensation in Lignin during Heating and Sulfuric Acid Treatment of Wood","subitem_title_language":"en"}]},"item_type_id":"4","owner":"13","path":["449"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-05-31"},"publish_date":"2007-05-31","publish_status":"0","recid":"5724","relation_version_is_last":true,"title":["Occurrence of Diphenylmethane Type Condensation in Lignin during Heating and Sulfuric Acid Treatment of Wood"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T02:22:14.560580+00:00"}
