Binary solvent mixtures of different (%) compositions have been prepared at 303.15 K using tetra alkyl ammonium iodides (R4NI) of 0.02 M to 0.14 M to investigate inter ionic interaction, ion-ion and ion solvent interactions in NMF-DMSO solvent mixture containing large cations of tetra alkyl ammonium iodides (R4NI). The densities (ρ0) of binary solvent mixtures and salt solutions have been measured by magnetic float densitometer. The apparent molar volume at infinite dilution фv0, in the solvent mixtures, have been utilized to estimate the apparent molar volumes of transfer ∆фv0 (tr), for various tetra alkyl ammonium iodide salts (R4NI) from NMF-DMSO mixtures. The observed trend and variations of dielectric constant and density with different (%) composition of NMF – DMSO provide useful information about the structural interactions.

使用磁浮密度仪测定NMF-DMSO混合物中某些R4NI盐溶液的密度,表观摩尔体积和转移的表观摩尔体积,然后研究303.15 K下的离子相互作用

已在303.15 K下使用0.02 M至0.14 M的四烷基碘化铵(R 4 NI)制备了不同(%)组成的二元溶剂混合物,以研究NMF-DMSO溶剂混合物中的离子间相互作用,离子与离子和离子与溶剂的相互作用包含四烷基碘化铵(R 4 NI)的大阳离子。密度(ρ 0的二元溶剂混合物和盐溶液)已经由磁性浮子密度计测量。在无限稀释ф表观摩尔体积v 0,在溶剂混合物中,已被用来估计传递Δф的表观摩尔体积v 0(TR),用于各种四烷基铵碘化物盐(R 4NI)来自NMF-DMSO混合物。随着NMF – DMSO组成的不同(%),观察到的趋势以及介电常数和密度的变化提供了有关结构相互作用的有用信息。
