Abstract
Pyridine and ethanenitrile can be used as molecular probes to measure the Lewis acidities of ionic liquids by monitoring the shift of IR absorption bands near 1450 cm(-1) for pyridine and in the range 2250-2340 cm(-1) for ethanenitrile.
摘要
吡啶和乙腈可用作分子探针，通过监测吡啶在1450 cm⁻¹附近以及乙腈在2250 - 2340 cm⁻¹范围内红外吸收带的位移来测量离子液体的路易斯酸度。
