Volumetric properties of (N,N-dimethylformamide+aliphatic diethers) at temperatures ranging from (298.15 to 358.15)K

Solvation of alkaline earth metal ions in N,N -dimethylformamide and N,N -dimethylacetamide – A volumetric and acoustic study

“…The sound velocity in dma was found to be (1455.82 ± 0.15) m Á s À1 while the literature values are in the range from (1455.37 to 1458) m Á s À1 [13,14,17,18,20,22]. As is seen from table 2, the experimental values for density and speed of sound of pure dmf and dma are in agreement with literature values over the whole temperature range T = (298.15 to 318.15) K [9,[12][13][14][15][16][17][18][19][20][21][22].…”

“…The experimental uncertainty of density and ultrasonic velocity measurements was better than 35.0 Á 10 À3 kg Á m À3 and 5 Á 10 À1 m Á s À1 , respectively. Before each measurement series, the accuracy of the density and sound velocity measurements and solvent purity were verified by measuring the density and sound velocity of pure dmf and dma at T = 298.15 K. The density values of (936.281 ± 0.019) kg Á m À3 for dma and (943.913 ± 0.018) kg Á m À3 for dmf were found in the present study while literature values vary from (936.24 to 937.0) kg Á m À3 for dma and (942.92 to 944.60) kg Á m À3 for dmf [9,[12][13][14][15][16][17][18]. The speed of sound obtained for dmf is (1457.17 ± 0.10) m Á s À1 while the corresponding literature values range from (1448.55 to 1469.5) m Á s À1 [13,14,[17][18][19][20][21].…”

Picosecond Solvation Dynamics of Coumarin153 in Bis(1-methyl-1H-imidazol-3-ium-3-yl)dihydroborate Cation Containing Room Temperature Ionic Liquid and Ionic Liquid-DMF Mixtures

“…It has been used to dissolve a wide range of organic and inorganic compounds which in turn has also made this solvent to be used in variety of industrial processes [27][28][29]. Moreover, it has been widely used in developing solvent reactivity relationships [30][31][32]. In view of this, it is expected that the RTIL-DMF will serve as an excellent solvent system for several applications.…”
