前言为了便于开展对乙烯装置裂解产物焦油综合利用的研究工作,我们用高压液体色谱法测定其族组成,并用毛细管色谱法对其主要组分进行了分析,取得了裂解焦油组成的基础性数据。用5μ硅胶[φ4(内径)×250mm]及无定型硅胶—氨基(φ4(内径)×250mm]作高压液体色谱柱,已烷作流动相,给出了饱和烃、单环芳烃、双环芳烃及胶质的族组成定量分析结果,相对误差3％。与柱色谱
Preface In order to facilitate the research on the comprehensive utilization of tar in ethylene plant cracked products, we determined its family composition by high pressure liquid chromatography and analyzed its main components by capillary chromatography. The basic data of cracking tar composition was obtained. Using 5μ silica [φ4 (inner diameter) × 250mm] and amorphous silica gel-amino (φ4 (inner diameter) × 250mm] as the high pressure liquid column, hexane was used as mobile phase to give saturated hydrocarbons, monocyclic aromatic hydrocarbons, bicyclic aromatic hydrocarbons and The composition of the colloidal composition quantitative analysis results, the relative error of 3%. And column chromatography
