Abstract: 采用FYX-2G型高压搅拌釜,在温度353~573K、压力2.0~10.0MPa、搅拌转速600r(min(1的实验条件下,根据气体等容吸收降压原理,测定了氢气在松脂和松香中的平衡溶解度.结果表明其溶解度随温度和压力的升高而增加,溶解度-压力曲线为通过原点的直线,符合Henry定律.在相同温度、压力下,氢气在松脂中的溶解度大于松香. 根据Vuuren提出的溶解度系数计算式,回归出溶解度系数与温度之间的关联式及溶解热:S松脂0.04459exp(-496.8/T),△Hsoln,m松指=4.1304kJ·mol-1;S松香=0.1885exp(-1360.8/T),△Hsoln,m松香=11.314 kJ·mol-1,为松脂、松香催化加氢反应机理研究和化学动力学模型的建立提供了基础数据.
