The following conditions were found to be favorable to prepare Al-MCM-41 with well ordered 2D-hexagonal structure from the reaction mixtures of lower Si/Al ratios: simultaneous addition of Si and Al sources into the solution containing both template of surfactant and anti-foaming agent, in neutral to acidic media (pH 3-7), at temperatures above Krafft point of the surfactant, and under vigorous stirring. These conditions may be associated with assembly of aluminosilicate sources with uniform composition (i.e., constant Si/Al ratio) around the template micelles, promoting hydrolysis and/or condensation of aluminosilicate and forming Al-MCM-41 with highly-ordered structures. Relatively weak acid sites are mainly consisted of Al-MCM-41 and similar distributions of acid strength are observed for the samples with different Si/Al species. Dealkylation reactions of 1,3,5-triisopropylbenzene, which are well known to proceed on Bronsted acid sites are catalyzed more effectively on Al-MCM-41 samples than on HY-zeolites. This means that at least, a part of Al was incorporated into the silica framework of MCM-41 structure as tetrahedrally coordinated species in Al-MCM-41 samples prepared in the present study.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Society of Materilas Engineering for resources of Japan","subitem_publisher_language":"en"}]},"item_10001_relation_25":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.5188/ijsmer.10.165","subitem_relation_type_select":"DOI"}}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1724099666130":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13479725","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA1095475X","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shindo, Takayoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kato, Masayoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kitabayashi, Shigeaki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"ijsmer10-2i.pdf","filesize":[{"value":"845.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ijsmer10-2i.pdf","url":"https://air.repo.nii.ac.jp/record/969/files/ijsmer10-2i.pdf"},"version_id":"1f2d8c93-c51a-44be-ae5d-1b00b29207d0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Mesoporous aluminosilicate MCM-41","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Non-hydrothermal synthesis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Preparation conditions","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Acidity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dealkylation of 1,3,5-triisopropylbenzene","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":"Several Factors Affectingthe Novel Synthesis of Mesoporous Aluminosilicate MCM-41 through Non-hydrothermal Conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Several Factors Affectingthe Novel Synthesis of Mesoporous Aluminosilicate MCM-41 through Non-hydrothermal Conditions","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["683"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-04-01"},"publish_date":"2008-04-01","publish_status":"0","recid":"969","relation_version_is_last":true,"title":["Several Factors Affectingthe Novel Synthesis of Mesoporous Aluminosilicate MCM-41 through Non-hydrothermal Conditions"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-08-25T10:42:27.357354+00:00"}
