近年来,用高效液相色谱法(HPLC)研究煤和石油等重质油品中的稠环芳烃虽已有些报导,但缺乏系统性和完整性,在定量测定中,尤为明显。我国在这方面的工作尚处于开始阶段,各种分析方法和实验数据有待建立和积累。我们以焦油等为主要对象,对其所含某些稠环芳烃组份,用HPLC法进行了研究。仪器和试剂仪器:日立635高效液相色谱仪,紫外200型检测器。色谱柱:5×250mm YWG-C_(18)H_(37)(天津试剂二厂生产)。实样:①炭黑焦油:山西太原钢铁公司样品。②用四氢萘抽提煤的液化产品(简称四氢萘-煤产品)。
In recent years, the use of high performance liquid chromatography (HPLC) to study heavy aromatic hydrocarbons in heavy oil such as coal and petroleum has been reported, but the lack of systematicness and completeness is particularly evident in the quantitative determination. Our country’s work in this area is still in its infancy, and various analytical methods and experimental data need to be established and accumulated. We use tar as the main target. Some of the PAHs contained in them are studied by HPLC method. Instruments and reagents Instruments: Hitachi 635 high performance liquid chromatography, UV detector 200. Column: 5 × 250mm YWG-C_ (18) H_ (37) (Tianjin Reagent Factory production). Really: ① carbon black tar: Shanxi Taiyuan Iron and Steel Company samples. ② extracted with tetrahydronaphthalene liquefaction products (referred to as tetralin - coal products).
