The limits were determined in a glass tube of 5cm. in internal diameter and 65cm. long, in which inflammable mixtures were ignited from the top by electric spark. The theoretical flame propagation temperatures were also calculated from the lower limits. The results showed that the lower limit of inflammability of ethyl alcohol, ethyl ether and methyl cyclohexane for open firing are 381%, 1.93% and 1.15% respectively, and that the theoretical flame propagation temperature of methyl cyclohexane are nearly the same as those of paraffin hydrocarbons, showing that the naphthene ring has no effect on the theoretical flame propagation temperatures of hydrocarbons. It was also shown that in all mixtures examined in this reseach, Le Chatelier's rule holds well the deviation being of much the same order as the experimental error.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4146399000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, Tokyo Imperial University"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00387631","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 芳雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"永井, 雄三郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"秋山, 金正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANAKA, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGAI, Yuzaburo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AKIYAMA, Kinsei","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA4146399.pdf","filesize":[{"value":"527.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4146399.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35249/files/SA4146399.pdf"},"version_id":"9d751acc-dbdd-4310-911b-aeecf5b7dff8"}]},"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":"Lower Limit of Inflammability of Ethyl Alcohol, Ethyl Ether, Methyl Cyclohexane and Their Mixtures.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Lower Limit of Inflammability of Ethyl Alcohol, Ethyl Ether, Methyl Cyclohexane and Their Mixtures.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1993"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35249","relation_version_is_last":true,"title":["Lower Limit of Inflammability of Ethyl Alcohol, Ethyl Ether, Methyl Cyclohexane and Their Mixtures."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:23:25.482468+00:00"}
