Experiments with glycerol and NaOH as reactants clarified the effects of temperature and initial molar ratio of glycerol to NaOH on the formation of lactate and by-products. Experiments with lactate and NaOH as reactants revealed the dehydration, decaboxylation and C–C cleavage of lactate. Fitting lines based on the kinetic model were in good agreement with the experimental data. Numerical simulations suggested that high selectivity of lactate could be achieved within a short reaction time under conditions of higher initial concentration of glycerol than NaOH at a temperature of 623 K.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"化学工学論文集. 42(4):148-154 (2016)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"長田, 光正","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.WmLUZFTp.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"化学工学会 "}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1252/kakoronbunshu.42.148"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1252/kakoronbunshu.42.148","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2016 公益社団法人化学工学会 "}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0386-216X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00037234","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"福村, 卓也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横田, 真実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長田, 光正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 和久"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-07-25"}],"displaytype":"detail","filename":"Kinetic_Analysis_Sodium_Lactate_Synthesis.pdf","filesize":[{"value":"490.1 kB"}],"format":"application/pdf","licensefree":"Copyright © 2016 公益社団法人化学工学会","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Kinetic_Analysis_Sodium_Lactate_Synthesis.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/18240/files/Kinetic_Analysis_Sodium_Lactate_Synthesis.pdf"},"version_id":"922c35de-4a8a-406b-9cef-c7b99b0f193e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"グリセリン","subitem_subject_scheme":"Other"},{"subitem_subject":"乳酸ナトリウム","subitem_subject_scheme":"Other"},{"subitem_subject":"高温アルカリ水","subitem_subject_scheme":"Other"},{"subitem_subject":"速度論モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"Glycerol","subitem_subject_scheme":"Other"},{"subitem_subject":"Sodium Lactate","subitem_subject_scheme":"Other"},{"subitem_subject":"High Temperature and Alkaline Aqueous Solution","subitem_subject_scheme":"Other"},{"subitem_subject":"Kinetic Model","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical Simulation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"反応速度論を用いた高温アルカリ水によるグリセリンからの乳酸ナトリウム合成反応の解析と最適条件の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"反応速度論を用いた高温アルカリ水によるグリセリンからの乳酸ナトリウム合成反応の解析と最適条件の検討","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["1310"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-07-25"},"publish_date":"2016-07-25","publish_status":"0","recid":"18240","relation_version_is_last":true,"title":["反応速度論を用いた高温アルカリ水によるグリセリンからの乳酸ナトリウム合成反応の解析と最適条件の検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:13:21.486147+00:00"}
