加圧化におけるしゅう酸カルシュームの熱分解 The Effect of Pressure on the Thermal Decomposition for Calcium oxalate Monohydrate 本間, 恒行 山田, 哲夫 佐々木, 満雄 application/pdf The effect of pressure on the thermal decomposition of calcium oxalate monohydrate　was examined according to TG and DTG curves by thermobalance　for pressure. The　pressure was controlled at 1，5，25 and 80 atm by using N_2，CO_2 and air.　The initial temperature of decomposition for CaC_2O_4･H_2O and CaCO_3 was constant　and the velocity of weight decrease of the thermal decomposition of CaC2O_4･H_2O and　CaCO_3 became smaller with increasing pressure except dissociation of CO_2 from CaCO_3　under atmosphere of CO_2.　　　　The initial temperature of decomposition of CaCO_3 became higher with increasing pressure of CO_2， but the velocity of weight decrease of the thermal decomposition of　CaCO_3 was constant in spite of increasing pressure of CO_2. The initial　temperature of decomposition and the velocity of weight decrease for　the dissociation　of CO from CaC_2O_4 were always constant，when a kind of gas and the　gas pressure were changed. 北見工業大学 1972-06 jpn departmental bulletin paper https://kitami-it.repo.nii.ac.jp/records/6297 北見工業大学研究報告 3 2 425 430 https://kitami-it.repo.nii.ac.jp/record/6297/files/3-2-18.pdf application/pdf 2.5 MB 2016-11-22
