| 摘 要： | 用四极质谱法测CCl_4的质谱。根据所测四氯化碳各种碎片离子的同位素分布比,计算出氯元素原子的平均原子量及CCl_4的平均分子量。结果表明:质谱法测得的CCl_4分子量比冻点下降法、蒸气密度法、……等所测CCl_4分子量的偏差小。

| Abstract: | The mass spectrum of ccl_4(carbon tetrachloride)was determined with quadrupole mass spectrometry, Based on the isotope distribution ratio of different fragments of ccl, the paper calculated the average atomic weight of chloride element and the average molecular weight of ccl~4. The experiment showed that the molecular weight of ccl_4 determined with mass spectrometry conforms to the standard value and its deviation is less than that of cryoscopic method, vapor densitymethoq etc. |
