合成了低黏度离子液体[Amim]Cl/ZnCl₂，并将其作为萃取剂对页岩油柴油中的碱性氮化物进行萃取脱除实验。考察不同温度、剂油质量比、时间下离子液体的脱氮效果。结果表明，反应温度为30℃，剂油质量比为1∶7，反应时间为20 min和沉降时间为2 h下，[Amim]Cl/ZnCl₂的脱氮率可达86%，且经过4次重复试验后仍能达到53%。

A low viscosity ionic liquid [Amim]Cl/ZnCl₂ is synthesized, and used as extractant to remove basic nitrogen compounds from shale oil diesel oil. The nitrogen removal efficiencies of this ionic liquid are investigated under different temperature, mass ratio of extractant to oil and extraction time. The results show that the removal rate of basic nitrogen compounds by [Amim]Cl/ZnCl₂ can reach 86% when the reaction temperature is 30℃, the mass ratio of extractant to oil is 1:7, reaction time sustains 20 minutes and settlement time takes 2 hours. After four times of repeated tests, the removal rate can still reach 53%.
