The absorbed toluene and carbon tetrachloride can be desorbed easily by evacuation above room temperature, and the absorption/desorption is completely reversible. The absorption/desorption phenomena were studied for the empty, partly and fully toluene and carbon tetrachloride absorbed samples by adiabatic calorimetry between 13K and 300K and by powder X-ray diffractiometry with high-energy synchrotron radiation at SPring-8 of JASRI. The first-order phase transition was observed in the empty sample. The partly toluene-absorbed samples showed smaller heat capacity anomaly at higher temperatures than the empty sample. On the other hand, the partly carbon tetrachloride-absorbed samples showed smaller heat capacity anomaly at lower temperatures than the empty sample. The difference in the two cases was discussed on the basis of structural and thermal data.","PeriodicalId":19096,"journal":{"name":"Netsu Sokutei","volume":"20 1","pages":"128-135"},"PeriodicalIF":0.0,"publicationDate":"2007-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81595100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
