Abstract

전자회로와 컴퓨터를 이용하여 액상가역반응의 반응경로로 추적할 수 있는 능동형 등온열량계를 개발하였고 무수 말레인산과 2-메틸 퓨란간의 딜스-알더반응이 디옥산용매에서 일어날 때 그축열능, 반응열, 반응평형정수 및 반응속도상수를 이 열량계로 ㅇ어진 응답곡선으로부터 추산하였다. 이 반응혼합물의 축열능은 온도 388^oK 무수 말레인산 초기농도 7.0mol/l에서 그 최대값 6.89J/cm³K로 측정되었다.

An active type isothermal calorimeter which can trace the progress of a liquid phase reversible reac-tion was constructed using electronic circuits and a digital computer. Heat storage capacity, heat of reaction, reaction equilibrium constant and reaction rate constants of a Diels-Alder reaction between maleic anhydride and 2-methyl furan in dioxane were estimated from the response curves of the calorimeter. The heat storage capacity of this mixture showed the maximum value of 6.89J/cm³K and 7.0mol/l initial concentration of maleic anhydride.
