The reaction was carried out in the liquid-solid system. Each ether used includes an atom having lone pairs, and the ethers are diethyl ether, 2,2’-dichlorodiethyl ether, and 1,2-dichloroethyl ethyl ether. In the exchange reaction, poly (vinyl alcohol) having T-labeled OH groups (i.e., OT group) was used as a solid sample material, and each ether dissolved in p-xylene was used as a liquid sample material. For comparison, Biphenyl ether was also used in this work (50-80℃). The concentration of the solution was set at 0.5 mol・dm-3, respectively. Based on the results obtained in this work, the following four have been clarified. (1) The reaction mass of diethyl ether is the same as that of 2,2’-dichloro diethyl ether, and the mass of 1,2-dichloroethyl ethyl ether is about 3/4 times that of the former two materials. (2) The H atoms bonded to a-carbon in each ether can participate in the T-for-H exchange reaction when they contact with T-labeled compound. (3) Comparing the rate constant for diphenyl ether with that for other materials previously obtained (by using the A\"-McKay plot method) , Biphenyl ether has a similar ability to aniline and benzaldehyde for causing this exchange reaction. In other words, H atoms bonded to a-carbon in certain ethers have a similar reactivity to those of both -NH2 in aniline and -CHO in benzaldehyde. (4) H atoms bonded to a-carbon in ethers seem to cause not only T-for-H exchange reaction, but also other chemical reaction (s).", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "37904", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Imaizumi, Hiroshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "37905", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishikawa, Satoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "37906", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Saito, Masaaki"}]}]}, "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_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": "今泉, 洋"}], "nameIdentifiers": [{"nameIdentifier": "37901", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "石川, 聡"}], "nameIdentifiers": [{"nameIdentifier": "37902", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "斎藤, 正明"}], "nameIdentifiers": [{"nameIdentifier": "37903", "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", "download_preview_message": "", "file_order": 0, "filename": "50_3_73-79.pdf", "filesize": [{"value": "564.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 564500.0, "url": {"label": "50_3_73-79.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2578/files/50_3_73-79.pdf"}, "version_id": "eebe28d5-a5d0-43f1-be6e-117c34ff38af"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "aliphatic ether", "subitem_subject_scheme": "Other"}, {"subitem_subject": "hydrogen atom bonded to α-carbon", "subitem_subject_scheme": "Other"}, {"subitem_subject": "reactivity of hydrogen atom", "subitem_subject_scheme": "Other"}, {"subitem_subject": "exchange reaction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "liquid-solid system", "subitem_subject_scheme": "Other"}, {"subitem_subject": "A\"-McKay plot", "subitem_subject_scheme": "Other"}, {"subitem_subject": "tritium", "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": "平衡下における脂肪族エーテルのα炭素上水素の反応解析 (T-for-H 交換の利用)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "平衡下における脂肪族エーテルのα炭素上水素の反応解析 (T-for-H 交換の利用)"}, {"subitem_title": "平衡下における脂肪族エーテルのα炭素上水素の反応解析 (T-for-H 交換の利用)", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/29849", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-09-10"}, "publish_date": "2014-09-10", "publish_status": "0", "recid": "2578", "relation": {}, "relation_version_is_last": true, "title": ["平衡下における脂肪族エーテルのα炭素上水素の反応解析 (T-for-H 交換の利用)"], "weko_shared_id": null}
