摘　　要：利用气相色谱法在石油产品分离方面的应用，以正戊烷作为标准物质，通过分析正戊烷保留时间、柱温调节和气体流速等影响因素，建立了气相色谱法分离测定液体石油产品族组成分析方法，研究了在测定液体石油产品烃类组成中影响测定结果的主要因素，结果准确，相对标准偏差在0．94％-3．60％范围内，所得到的分析结果有利于今后液体石油产品的分离研究。Based on the application of gas chromatography in the separation of petroleum products, using n-pentane as the standard substance, regulating effect factors such as n-pentane retention time, gas flow rate and column temperature were analyzed, a gas chromatographic method was established for the separation and determination of the family composition of liquid petroleum products. The main factors affecting the determination results of hydrocarbon composition in liquid petroleum products were studied and the result was accurate. Relative standard deviated in the range of 0. 94% - 3.60%. The obtained results were beneficial to the separation of liquid petroleum products in the future.
