摘要
本文在20—130大气压范围内测定了20.0℃、39.6℃、54.6℃和70.0℃温度下氮气在正辛烷-异辛烷混合溶剂中的溶解度.温度和溶剂组成一定条件下,所测结果可用最小二乘法拟合成Inx_(N_2)=A+Bp_(N_2)+Cp_(N_2)~2+Dlnp_(N_2)的形式.根据溶解度与压力的关系,计算了氮在溶液中的偏摩尔体积和亨利常数。
Solubilities of nitrogen in binary mixtures of n-octane and iso-octane have beenmeasured over the temperature range of 20 to 70℃ and at pressures up to 130 atm.Experimental results can be fitted by the following equation lnx_(N_2)=A+Bp_(N_2)+Cp_(N_2)~2+DlnpFrom the experimental results, the partial molar volume of dissolved nitrogen andthe Henry's law constants have been calculated.
