恩氏蒸馏法在溶剂油馏程测定中的应用

摘要

恩氏蒸馏法用于对溶剂油产品馏程的相对比较或对油品中轻重馏分相对含量作大致判断。在本实验中，五种溶剂油产品的所测馏程均在标准馏程范围内，并且随着馏出物的体积百分比增加，温度也随之增加，但达到一定温度后不再上升，此温度即为干点。%Engler distillation is used for comparing the boiling range of solvent oil or judging the relative content of fractions in the oil. In this experiment, the measured boiling range of five solvent oils were in the standard, and with the distillate percentage volume increased, the temperature also increased, but when the temperature reached a certain point and no longer raised, this temperature was the final boiling point.
