Since use of heavy metals, such as Te or Pb, is inconsistent with green chemistry, a heavy-metal-free Pd/C catalyst is employed in the present study. The oxidative dehydrogenation of sodium lactate to sodium pyruvate in an aqueous phase at 358 K under pressurized oxygen at 1 MPa proceeded favorably using Pd/C with no adjustment of solution pH. Under pressurized oxygen, the catalytic activity of Pd/C was similar to that of Pd/C doped with either Te or Pb. This result suggests that a heavy-metal-free Pd/C catalytst might also be applied to other catalytic reactions. As an alternative to doping Pd/C with Te or Pb, the dissolution of gaseous oxygen into the reaction solution significantly enhanced the catalytic activity of Pd/C. To show the contribution of the dissolution of gaseous oxygen, the effects of the volume of oxygen in the reactor (stainless autoclave) on the reaction rate and the activity were examined. The activation parameters thus obtained reveal that the volume of oxygen in the reactor is a more important determinant of catalytic activity than the activation of the reaction itself.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"Copyright © 2010 The Society of Chemical Engineers, Japan","subitem_rights_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"00219592","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00709658","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1722929371688":{"attribute_name":"出版社版DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"10.1252/jcej.43.514"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1252/jcej.43.514","subitem_relation_type_select":"DOI"}}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"207207"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"杉山, 茂","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"67","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中, 春樹","creatorNameLang":"ja"},{"creatorName":"タナカ, ハルキ","creatorNameLang":"ja-Kana"},{"creatorName":"Tanaka, Haruki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"菊本, 哲雄","creatorNameLang":"ja"},{"creatorName":"キクモト, テツオ","creatorNameLang":"ja-Kana"},{"creatorName":"Kikumoto, Tetsuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中川, 敬三","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"外輪, 健一郎","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"1229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前原, 桂子","creatorNameLang":"ja"},{"creatorName":"マエハラ, ケイコ","creatorNameLang":"ja-Kana"},{"creatorName":"Maehara, Keiko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"二宮, 航","creatorNameLang":"ja"},{"creatorName":"ニノミヤ, ワタル","creatorNameLang":"ja-Kana"},{"creatorName":"Ninomiya, Wataru","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2017-03-25"}],"displaytype":"detail","filename":"LID201703242004.pdf","filesize":[{"value":"284 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2003253/files/LID201703242004.pdf"},"version_id":"e5c88336-1e50-4f90-9c00-68db61dfdd2d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Oxidative Dehydrogenation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sodium Lactate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sodium Pyruvate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pd/C","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressurized Oxygen","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Application of Heavy-Metal-Free Pd/C Catalyst for the Oxidative Dehydrogenation of Sodium Lactate to Pyruvate in an Aqueous Phase under Pressurized Oxygen","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of Heavy-Metal-Free Pd/C Catalyst for the Oxidative Dehydrogenation of Sodium Lactate to Pyruvate in an Aqueous Phase under Pressurized Oxygen","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"7","path":["1713853295607"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-03-24"},"publish_date":"2017-03-24","publish_status":"0","recid":"2003253","relation_version_is_last":true,"title":["Application of Heavy-Metal-Free Pd/C Catalyst for the Oxidative Dehydrogenation of Sodium Lactate to Pyruvate in an Aqueous Phase under Pressurized Oxygen"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2024-10-28T01:34:33.363309+00:00"}
