The total heat of wetting of wood which is extracted with cold water, alcohol-benzene, acidified sodium chlorite solution and 0.2% oxalic acid aqueous solution, was measured by using a twin-type conduction microcalorimeter. The results obtained are as follows : (1) Except for a few species, the total heat of wetting of wood extracted with alcohol-benzene is higher than that of untreated wood. (2) The total heat of wetting increases with the decrease in lignin content. This inclination is found to be much more remarkable in the short time of treatment. The total heat of wetting of lignin is determined from percentage of lignin removed under each treating time, the total heat of wetting of extractive-free wood and of various delignified wood; the values depend on the treating time. Therefore, additivity rule does not hold good in this case. (3) The total heat of wetting of holocellulose decreases with the decrease in hemicellulose content. The total heat of wetting of hemicellulose are determined from weight loss and the total heat of wetting of various holocellulose samples; the values are about the same as that of isolated hemicellulose sample.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"梶田, 煕","creatorNameLang":"ja"},{"creatorName":"カジタ, ヒロム","creatorNameLang":"ja-Kana"},{"creatorName":"Kajita, Hiromu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078988.pdf","filesize":[{"value":"803.9 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078988.pdf","url":"https://kpu.repo.nii.ac.jp/record/4989/files/KJ00000078988.pdf"},"version_id":"72f6194d-ff23-4904-96b1-d50250f053c1"}]},"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"}]},"item_title":"木材-水系の湿潤熱 (III)(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"木材-水系の湿潤熱 (III)(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["421"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4989","relation_version_is_last":true,"title":["木材-水系の湿潤熱 (III)(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-10T06:11:35.216090+00:00"}
