A decarbonation system for carbonate samples such as shells and corals was additionally installed into the benzene synthetic system in order to measure carbonate ^<14>C-ages. We used 10 benzene samples, such as buried woods, charcoal, commercial cokes and fossil shells to measure ^<14>C using a liquid scintillation counter. The yields of these 10 samples during sample combustion were more than 99% after correction for the charcoal carbon content, and during decarbonation were 69〜94% with a mean value of 84%. The yields from carbon dioxide into acetylene were 80〜96% with a mean value of 90%, and from acetylene into benzene were 76〜95% with a mean value of 86%. Carbon isotopic fractionation during combution into CO_2 from charcoal samples was less than 1%o and that through the whole procedure of benzene synthesis was about ±3‰. The purity of benzene synthesized was 98.7〜99.9% by NMR and there were no impurities such as acetone, or ethyl alcohol, but 0.06〜1.34% toluene was detected. Using this system, a buried wood sample collected from the Kawagodaira pyroclastic flow was synthesized into benzene. The measured ^<14>C-age was 3,400±80 y B.P., which was slightly older than before reported.","subitem_description_type":"Abstract"}]},"item_25_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14945/00000338","subitem_identifier_reg_type":"JaLC"}]},"item_25_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"静岡大学地球科学教室"}]},"item_25_relation_22":{"attribute_name":"NII論文ID","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110000413368","subitem_relation_type_select":"NAID"}}]},"item_25_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03886298","subitem_source_identifier_type":"ISSN"}]},"item_25_source_id_23":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00103190","subitem_source_identifier_type":"NCID"}]},"item_25_subject_8":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"450","subitem_subject_scheme":"NDC"}]},"item_25_version_type_32":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"福原, 達雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"猪俣, 和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 秀樹"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-14"}],"displaytype":"detail","filename":"KJ00000102394.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000102394.pdf","url":"https://shizuoka.repo.nii.ac.jp/record/408/files/KJ00000102394.pdf"},"version_id":"86dae1e4-fc5e-4535-94d5-57232388c4e0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"^<14>C dating","subitem_subject_scheme":"Other"},{"subitem_subject":"benzene synthesis","subitem_subject_scheme":"Other"},{"subitem_subject":"liquid scintillation method","subitem_subject_scheme":"Other"},{"subitem_subject":"isotopic fractionation","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":"静岡大学における^<14>C年代測定用ベンゼン合成法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"静岡大学における^<14>C年代測定用ベンゼン合成法"}]},"item_type_id":"25","owner":"3","path":["109"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-25"},"publish_date":"2008-01-25","publish_status":"0","recid":"408","relation_version_is_last":true,"title":["静岡大学における^<14>C年代測定用ベンゼン合成法"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-02-19T05:40:22.906541+00:00"}
