The antioxidative activity of the compounds added to polypropylene as 0.005 wt% was examined by the melt-index and yellow index methods. The compounds had onlyantioxidative activity. The antioxidative activity significantly increased mixing with phenolic and phosphoric antioxidants. Investigation of the mechanism of the antioxidative activity revealed that hydrocarbon radicals produced by the thermal decomposition of polypropylene or polyethylene immediately reacted with the antioxidant to form stable product. The S-13 or S-19 antioxidants were regenerated by the reaction between the antioxidant radicals, and phenolic and phosphoric antioxidants.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"シクロヘキサノンオキシムの気相ベックマン転位反応において触媒活性劣化に及ぼす細孔径の影響を明らかにするため，MFI構造をもつTS-1およびこれよりも大きな細孔をもつSSZ-31およびSSZ-24を触媒として反応を行った。SSZ-24を用いたときの活性劣化定数は，本研究で使用したゼオライトの中で最大になった。さらに，ε-カプロラクタムの分子径/ゼオライトの細孔径比が1になるとき，同程度の酸性度をもつゼオライト間で最大の活性劣化因子をもつことが分かった。これらの結果は，細孔内の活性点で生成したε-カプロラクタムが細孔から拡散できないため，ε-カプロラクタムが長時間にわたり細孔内に滞留し，結果としてコークあるいはその前駆体になったことを示唆している。ゼオライトの細孔径はベックマン転位反応の活性劣化に大きな影響を与えた。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"石油学会","subitem_publisher_language":"ja"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1627/jpi.49.121","subitem_relation_type_select":"DOI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人石油学会","subitem_rights_language":"ja"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13468804","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11590615","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"568","subitem_subject_scheme":"NDC"},{"subitem_subject":"571","subitem_subject_scheme":"NDC"}]},"item_6_subject_20":{"attribute_name":"NIIsubject","attribute_value_mlt":[{"subitem_subject":"化学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"プロセス工学・化学工学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_6_version_type_14":{"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":"勝山, 和樹","creatorNameLang":"ja"},{"creatorName":"Katsuyama, Kazuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井上, 健","creatorNameLang":"ja"},{"creatorName":"Inoue, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高橋, 武重","creatorNameLang":"ja"},{"creatorName":"Takahashi, Takeshige","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"甲斐, 敬美","creatorNameLang":"ja"},{"creatorName":"Kai, Takami","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":"2016-10-27"}],"displaytype":"detail","filename":"jpi_2006_49_3.pdf","filesize":[{"value":"485.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jpi_2006_49_3.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/1616/files/jpi_2006_49_3.pdf"},"version_id":"4676fd7c-8852-4ac7-84ec-0dcf4c99596b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Polyolefin resin","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Oxidative fouling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antioxidant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Vitamin E related compound","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Radical suppression","subitem_subject_language":"en","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":"ポリオレフィン樹脂の酸化防止に対するビタミンE類似化合物の添加による相乗効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポリオレフィン樹脂の酸化防止に対するビタミンE類似化合物の添加による相乗効果","subitem_title_language":"ja"},{"subitem_title":"Synergistic Effect of Vitamin E Related Additives on Antioxidation of Polyolefin Resin","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["67"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-02-09"},"publish_date":"2015-02-09","publish_status":"0","recid":"1616","relation_version_is_last":true,"title":["ポリオレフィン樹脂の酸化防止に対するビタミンE類似化合物の添加による相乗効果"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T05:03:48.676984+00:00"}
