| 摘 要： | 测定乙酸乙酯—四氯化碳溶液的介电常数和折光率,通过计算获得溶液的密度.根据Clausius-Mosotti-Debye方程,求出乙酸乙酯的偶极矩为1.79D,与文献值(1.78D)非常接近.此法具有操作简便,耗样量少,低毒性,速度快,实验数据线性好和结果准确度高等特点.

| Abstract: | The solution density of acetic ether in the carbon tetrachloride solution is obtained by calculation of the dielectric constant and refraction index determined.According to the Clausius-Mosotti-Debye equation,the dipole moment of the acetic ether is obtained to be 1.79D,which is close to the literature value.This method takes on briefness and expedience,consuming a little dosage,having the low toxicity,fast velocity.The experiment date have fine linear and high accuracy result and so on. |
