摘　　要：用恩氏蒸馏分析石脑油的馏程和干点时间长、污染大、操作复杂。通过统计分析色谱模拟蒸馏与恩氏蒸馏的数据,得出了两者之间的关联公式,利用将色谱模拟蒸馏数据代入该公式计算出石脑油的干点,计算得到的石脑油干点数据与恩氏蒸馏结果吻合,实现了使用色谱模拟蒸馏分析石脑油的馏程和干点。Using Engler distillation method to analyze the distillation range and dry point of naphtha has long time,high pollution and complex operation.Through statistical analysis of the data of chromatographic simulation distillation and Engler distillation,the correlation formula between them was obtained.The dry point of naphtha was calculated by substituting the simulated distillation data into the formula,and the calculated dry point of naphtha was in good agreement with the engler distillation results.The distillation range and dry point of naphtha were analyzed by chromatographic simulation distillation.
