Thermodynamics of acrylic ester-organic solvent mixtures. V. viscosities and excess viscosities of alkyl acrylates-1-alcohol binary mixtures at 298.15 and 308.15 K

Measurements of densities, viscosities, speeds of sound and relative permittivities and excess molar volumes, excess isentropic compressibilities and deviations in relative permittivities and molar polarizations for dibutyl ether+benzene,+toluene and+p-xylene at different temperatures

“…Our laboratory has been actively engaged in reporting various thermophysical properties of binary and ternary mixtures consisting of acrylic esters + 1-alcohols [1][2][3][4][5][6][7][8][9], + alkoxyethanols [6,7] and + aliphatic [9][10][11][12][13][14] and aromatic [15,16] hydrocarbons. Such studies have tremendous academic and industrial importance.…”

Excess volumes and dielectric properties for (methyl methacrylate + a branched alcohol) atT= 298.15 K andT= 308.15 K

“…The V E m values at x 1 = 0.5 of (0.2607 and 0.3128) µm 3 · mol −1 (MMA + propan-2-ol) and (0.5260 and 0.5739) µm 3 · mol −1 for (MMA + butan-2-ol) at T = (298.15 and 308.15) K are more positive than the V E m values of (−0.1330 and −0.1680) µm 3 · mol −1 for (MMA + propan-1-ol) and (0.4610 and 0.3670) µm 3 · mol −1 for (MMA + butan-2-ol) (1) at the same temperatures. The more positive V E m values in (MMA + propan-2-ol) and butan-2-ol mixtures relative to (MMA + corresponding 1-alcohol) can be attributed to the fact that branching in the alcohols decreases the negative contributions to V E m values.…”

“…Our previous publications (1)(2)(3)(4)(5) dealt with measurements of various thermophysical properties (acrylic ester + 1-alcohols). It has been found that two opposing effects namely specific interactions between the ester and -OH group of 1-alcohol (or packing effects due to the interactions between the π electrons of the ester and -OH group of 1-alcohols) and nonspecific dispersion interactions, i.e.…”

Excess volumes, relative permittivity increments, and excess molar polarizations of { x CH2CCH3CO2CH3+ (1−x) ( C6H6, or C7H8, or o -C8H10, or m -C8H10, or p - C8H10, or C8H10, or c -C6H12)}

“…Thus, the measurements of the thermophysical properties of binary and ternary mixtures involving acrylic esters, hydrocarbons, and 1-alcohols are useful not only in providing vital process parameters for the efficient design of transesterification processes but also for the determination of group interaction parameters for the development of semi-empirical models based on group contribution methods. In an effort to make available thermophysical properties of (acrylic esters + hydrocarbons), our laboratory has reported excess volumes and excess isentropic compressibilities, (1)(2)(3) viscosities, (4,5) and relative permittivity and molar polarizations (6,7) for the acrylic esters of either methyl acrylate, or methylmethacrylate with aliphatic, chlorinated hydrocarbons and 1-alcohols.…”
