摘要
寻找并配制苯甲腈和正十四烷溶液的临界温度和临界组成,用折射率方法测定共存曲线.在离临界温度11.4 K范围内测定了温度-折射率数据,通过计算临界指数β和指前因子B,结果与3D-Ising模型的理论值一致.
The critical components and critical temperature of（ benzonitrile ＋ tetra- decane） have been found and made up of. The temperature- refractive index（ T,n） coexistence curve of the critical binary solution has been determined within 11. 4 K from the critical temperature by measuring refractive index. The critical exponent β and the critical amplitude B have been deduced by the linear least- squares fitting,and the result is consistent with the theoretical prediction of the 3D- Ising model.
