This work is devoted to study the extraction dearomatization of the kerosene fraction using ionic liquids synthesized on the basis of formic acid and morpholine, as well as acetic acid and diethylamine as a selective solvent. The influence of various factors on the selective purification process has been investigated and the conditions for dearomatization of kerosene have been determined. The group hydrocarbon composition of the dearomatized kerosene raffinate samples by ion-liquid extraction was determined by IR and UV spectral analysis.

通过红外和紫外光谱分析研究煤油的脱芳构化

本工作致力于研究以甲酸和吗啉为基础合成的离子液体，以乙酸和二乙胺为选择性溶剂，对煤油馏分进行萃取脱芳构化。研究了各种因素对选择性提纯过程的影响，并确定了煤油脱芳构化的条件。通过IR和UV光谱分析确定了离子液体萃取脱芳构化煤油残液样品的基团烃组成。
