标准摘要
[中文适用范围]: 本文件规定了一种测定常压下沸点在 30°C 至 300°C 之间、化学性质稳定且在蒸馏过程中不会腐蚀设备的液体沸程的方法。该方法适用于有机液体,如烃类、酯类、醇类、酮类、醚类和类似产品。注 1:在蒸馏瓶的容积、冷却器类型和蒸馏接收器方面,该方法与 ISO 918 中描述的方法不同。注 2:在蒸馏瓶的容积和瓶支架孔径方面,该方法与 ISO 3405 中规定的方法不同。 [外文原描述]: This document specifies a method for determining the boiling range of liquids that boil between 30 °C and 300 °C at normal pressure, and that are chemically stable and do not corrode the apparatus during the distillation. The method is applicable to organic liquids such as hydrocarbons, esters, alcohols, ketones, ethers and similar products. NOTE 1 The method differs from that described in ISO 918 with respect to the volume of the distillation flask, the type of cooler and the distillation receiver. NOTE 2 The method differs from that specified in ISO 3405 with respect to the volume of the distillation flask and the diameter of the hole in the flask support.
