In this study, the enthalpy change ΔH, Gibbs energychange ΔG, entropy change ΔS, and equilibrium constants K for the isomerization reactions of butenes C4H8(1-butene ⇄ 2-metylpropene, 1-butene ⇄ trans-2-butene, cis-2-butene ⇄ 2-methylpropene, and cis-2-butene⇄ trans-2-butene) under standard conditions (298. 15 K, 10 5Pa) were calculated and physicochemical properties on these reactions were discussed. It has suggested that the reaction in which 1-butene is isomerized to 2-methylpropene is irreversible, both 1-butene to trans-2-butene and cis-2-butene to 2-methylpropene arealmost irreversible, and cis-2-butene to trans-2-butene is reversible. The relationship between Gibbs energy change without considering the effect of mixing ΔGo and the extent of reaction at chemical equilibrium αe is investigated, and it has found that if ΔGo is less than -13 kJ-mol-1, then αe ≈ 1 mol and the reaction is irreversible with almost complete progress. The results of this study will be useful as teaching materials for high school chemistry and can be used in high school-university connection learning programs.","subitem_description_type":"Other"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18878/0002000331","subitem_identifier_reg_type":"JaLC"}]},"item_10002_select_43":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10002_text_31":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"神戸女学院大学研究所"}]},"item_10002_text_47":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"神戸女学院大学 人間科学部 環境・バイオサイエンス学科 教授"}]},"item_10002_text_48":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_text_value":"AN00085725"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中川, 徹夫","creatorNameLang":"ja"},{"creatorName":"NAKAGAWA, Testuo","creatorNameLang":"en"},{"creatorName":"ナカガワ, テツオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3645","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000070312866","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000070312866"},{"nameIdentifier":"70312866","nameIdentifierScheme":"KAKEN-研究者検索","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/10000##/"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-07-02"}],"filename":"202406_192-04.pdf","filesize":[{"value":"945 KB"}],"format":"application/pdf","license_note":"神戸女学院大学研究所","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://kobe-c.repo.nii.ac.jp/record/2000331/files/202406_192-04.pdf"},"version_id":"056546c5-ce00-4012-8349-eadbf2baa6b0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"異性化反応","subitem_subject_scheme":"Other"},{"subitem_subject":"ブテン","subitem_subject_scheme":"Other"},{"subitem_subject":"エンタルピー変化","subitem_subject_scheme":"Other"},{"subitem_subject":"ギブズエネルギー変化","subitem_subject_scheme":"Other"},{"subitem_subject":"平衡定数","subitem_subject_scheme":"Other"},{"subitem_subject":"isomerization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"butene","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"enthalpy change","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Gibbs energy change","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equilibrium constant","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ブテン異性化反応の特性に関する検討 ― エンタルピー変化、ギブズエネルギー変化、エントロピー変化および平衡定数の推算 ―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ブテン異性化反応の特性に関する検討 ― エンタルピー変化、ギブズエネルギー変化、エントロピー変化および平衡定数の推算 ―","subitem_title_language":"ja"},{"subitem_title":"Investigation on Characteristics of Butene Isomerizations: Estimation of Enthalpy Changes, Gibbs Energy Changes, Entropy Changes and Equilibrium Constants","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"21","path":["1719537819096"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-07-02"},"publish_date":"2024-07-02","publish_status":"0","recid":"2000331","relation_version_is_last":true,"title":["ブテン異性化反応の特性に関する検討 ― エンタルピー変化、ギブズエネルギー変化、エントロピー変化および平衡定数の推算 ―"],"weko_creator_id":"21","weko_shared_id":-1},"updated":"2024-08-27T01:03:27.196792+00:00"}
