摘要
采用改进的Ellis平衡釜和毛细管气相色谱分析方法,测定了常压及在真空度0.01331~0.0399MPa、温度501.19~527.55K条件下高浓度长叶烯体系的汽液平衡数据,根据稀溶液的溶剂符合Raoult定律的规则,由Raoult定律计算出上述实验温度下长叶烯的饱和蒸汽压,然后使用EVIEWS数理统计软件回归出Antoine方程的各参数,回归相关系数达0.9999,从而建立了长叶烯饱和蒸汽压与温度的关联式,其计算值与实验结果的相对误差范围为0.038%~0.34%.
The vaporliquid equilibrium data of high concentration longifolene system were determined at atmospheric pressure , varies vacuums ranging from 0.013 31 MPa to 0.039 9 MPa and 501.19~527.55 K by using the modified Ellis still and capillary tube gas chromatograph analysis method. Based on the regulation that the solvent in dilute solution accords with Raoult's law, the saturated vapor pressures of longifolene at experimental temperatures were calculated by Raoult's law, respectively. The Antoine parameters have been regressed by using the EVIEWS software. The RSquares are up to 0.999 9.The relationship between saturated vapor pressure and temperature for longifolene is obtained, and the calculated relative error is 0.038%~0.34%.
