As a result, the radioactivity of the compounds was increased with the reaction time. Applying the A\"-McKay plot method to the observed data obtained, the rate constants (k) of the functional groups in each compound were obtained. Comparing k with each other, the following seven matters have been clarified, (1) The reactivity of substituted hydroxybenzoic acid (and carboxylic acid) depends on temperature. (2) The reactivity of each functional group in the liquid-solid system is about 7 to 12 times the reactivity in the gas-solid system. (3) The reactivity of a certain substituted benzoic acid may be twice as large as that of another substituted one by resonance effect. (4) Applying the A\"-McKay plot method, the reactivity of substituted hydroxybenzoic acids can be clarified under the condition of non-masking reagent. (5) The exchange reaction under a general environment can be inferred based on this work. (6) The reactivity of the carboxyl groups of the substituted hydroxybenzoic acid can be deduced by applying the Hammett rule. (7) The method used in this work is useful for evaluating the influence of T to environment.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"37812","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tamura, Kiyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"37813","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Imaizumi, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"37814","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kano, Naoki"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本アイソトープ協会"}]},"item_5_relation_37":{"attribute_name":"部分である","attribute_value_mlt":[{"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10191/7010","subitem_relation_type_select":"URI"}}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00351589","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00338303","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田村, 潔"}],"nameIdentifiers":[{"nameIdentifier":"37809","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今泉, 洋"}],"nameIdentifiers":[{"nameIdentifier":"37810","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"狩野, 直樹"}],"nameIdentifiers":[{"nameIdentifier":"37811","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"2009030061.pdf","filesize":[{"value":"848.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2009030061.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2566/files/2009030061.pdf"},"version_id":"6590fe6f-788e-4b7a-b61b-82d94878372c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"aliphatic cyclic alcohol","subitem_subject_scheme":"Other"},{"subitem_subject":"carboxylic acid","subitem_subject_scheme":"Other"},{"subitem_subject":"T-for-H exchange reaction","subitem_subject_scheme":"Other"},{"subitem_subject":"functional group","subitem_subject_scheme":"Other"},{"subitem_subject":"A\"-Mckay plot method","subitem_subject_scheme":"Other"},{"subitem_subject":"liquid-solid reaction","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":"T-for-H交換反応における脂環式アルコール及びカルボン酸の速度論的反応解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"T-for-H交換反応における脂環式アルコール及びカルボン酸の速度論的反応解析"},{"subitem_title":"T-for-H交換反応における脂環式アルコール及びカルボン酸の速度論的反応解析","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-06"},"publish_date":"2009-04-06","publish_status":"0","recid":"2566","relation_version_is_last":true,"title":["T-for-H交換反応における脂環式アルコール及びカルボン酸の速度論的反応解析"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:42.358131+00:00"}
