标准范围

本方法适用于在常压下在30至300℃之间沸腾的有机液体，以及在蒸馏过程中化学稳定且不会腐蚀设备的有机液体，如碳氢化合物、酯、醇、酮、醚和类似产品。该原理包括在规定条件下蒸馏100 ml试验部分，系统观察温度计读数和冷凝液体积，并根据这些数据计算结果，并校正至标准大气压力。

This method is applicable to organic liquids that boil between 30 and 300 C at normal pressure, and that are chemically stable and do not corrode the apparatus during the distillation such as hydrocarbons, esters, alcohols, ketones, ethers and similar products. The principle consists in distillation of a 100 ml test portion under prescribed conditions, systematic observation of thermometer readings and volumes of condensate and calculation of the results from these data with correction to standard atmospheric pressure.
