액상 가역반응의 열에너지 저장능력
Thermal Energy Storage Capacity of Reversible Liquid Phase Reaction
초록
등온 열량계의 설정점을 변하여 액상 가역반응 혼합물의 열에너지 저장능력을 측정할 수 있었다. 298K와 368K사이의 넓은 온도범위에서 얻어진 이 지장능력으로부터 반응열과, 그 반응의 가역성 때문에 직접은 측정키 어려운 생성물의 열룡량들을 그 결과를 통계분석하여 결정하였다. 2-메틸 퓨란과 무수 말레산간의 반응열과 첨가생성물의 열용량은 각각 61,200J/molK와 2.38±0.254J/gK였는데 이 반응열은 이전의 연구자들의 결과보다 약간 높았다. Methyl ethyl Ketone, acetone 및 iso-butyraldehyde가 sodium bisulfite와 수용액중에서 반응하여 술폰화합물이 될 때의 열에너지 저장능력들도 측정하여 보고하였다.
By means of a set point change in an isothermal calorimeter the thermal energy storage capacity of the reversible liquid phase reaction mixture could be measured. From the storage capacities obtained in the wide range of temperatures between 298 and 368K the heat of reaction and the heat capacities of the product species, which would be difficult to measure directly because of the reversibility, were determined by analyzing the results statistically. The heat of reaction between 2-methyl furan and maleic anhydride and the heat capacity of the adduct were 61,200J/molK and 2.38±0.254J/gK, respectively. The former was found to be slightly higher than that of previous workers. The storage capacities for the aqueous reaction of methyl ethyl ketone, acetone, and iso-butyraldehyde with sodium bisulfite were reported too.
