15–318.15) K and at atmospheric pressure. From density data the apparent molar volumes and partial molar volumes of the ILs at infinite dilution as well as the limiting apparent molar expansibilities and the Hepler’s constant values have been evaluated. The results have been discussed in terms of the effect that alkyl chain length of the ILs and experimental temperature have on the ionic liquid–acetonitrile
基于N-烷基-N-甲基-吗啉阳离子,N-乙基-N-甲基吗啉鎓双(三氟甲磺酰基)酰亚胺,N-丁基-N-甲基吗啉鎓双(三氟甲烷磺酰基)酰亚胺,N-甲基的离子液体的一些乙腈溶液的密度- ñ -octylmorpholinium双(三氟甲烷磺酰)亚胺和ñ -decyl- ñ -methylmorpholinium双(三氟甲烷磺酰)亚胺物在测定Ť=(298.15–318.15)K,在大气压下。从密度数据中,已评估了无限稀释下IL的表观摩尔体积和部分摩尔体积,以及极限表观摩尔膨胀率和Hepler常数。就IL的烷基链长度和实验温度对所研究溶液中发生的离子液体-乙腈相互作用的影响进行了讨论。
