色谱法同时测定石油甲苯馏程和纯度

Simultaneous Determination of Boiling Range and Purity of Petroleum Toluene by Gas Chromatography(GC)

色谱法同时测定石油甲苯馏程和纯度李向前（抚顺石油化工公司研究院抚顺１１３００６）１前言馏程和杂质的测定普遍用于甲苯的生产控制与质量检测中。分别测定的这两个独立的方法，费工费时。本法试用同一条件同时测定馏程和纯度，效果极佳。本法适用于常减压直馏产品为原...

his paper describes the conditions of GC analysis of petroleum toluene and the method of data process-ing.This method can simultaneously determine boiling range and purity of petroleum toluene,and its opera-tion is simple practical and suitable for computer operation. The data obtained proved that this method completely satisfies the required precision of National Stan-dard Methods.
