摘要：使用高压搅拌釜，在６０～２３０°Ｃ、０．１５～１．３ＭＰａ条件下测定了文题的反应及惰性组分Ｏ２、Ｃ２Ｈ４、ＣＯ２和Ｎ２在高沸点溶剂中的溶解度，采用０．１５级精密压力变送器，根据高压釜中各纯气体溶解前后压力的变化值计算出该温度及压力下的溶解度。发现，Ｏ２、Ｃ２Ｈ４、ＣＯ２和Ｎ２的平衡溶解度都随压力增加而增大；Ｏ２、Ｃ２Ｈ４和ＣＯ２的平衡溶解度随温度升高而降低，Ｎ２的平衡溶解度随温度升高而增大。回归出各气体的溶解度系数Ｈｉ与温度ｔ的关联方程。
Equilibrium solubilities (C*) of O_2, CO_2, C_2H_4 and N_2 in high boiling point solvent were measured at elevated temperatures of 60-230°C and under pressures of 0.15-1.3MPa in an agitated autoclave. According to the change of pressures during the pure gas solution in the solvent, solubilities for O_2,CO_2,C_2H_4 and N_2 were calculated. Under operating conditions, the C* of O_2, CO_2, C_2H_4 and N_2 in the solvent increased with pressure. Solubilities for O_2,CO_2 and C_2H_4 decreased with an increase in temperature but that of N_2 increased with temperature. The relationships of solubility coefficient for O_2,CO_2,C_2H_4 and N_2 with temperature were correlated.
