Densities, viscosities, sound speeds, and excess properties of binary mixtures of methyl methacrylate with alkoxyethanols and 1-alcohols at 298.15 and 308.15 K

The densities, viscosities, and sound speeds were measured for six binary m ixtures of methyl methacrylate (MMA) +2-methoxyethanol (ME), +2-ethoxyethan ol (EE), +2-butoxyethanol (BE), +1-butanol (1-BuOH), +1-pentanol (1-PeOH), and +1-heptanol (I-HtOH) at 98.15 and 308.15 K. The mixture viscosities wer e correlated by Grunberg-Nissan, McAllister, and Auslander equations. The s ound speeds were predicted by using free length and collision factor theore tical formulations, and Junjie and Nomoto equations. The excess viscosities and excess isentropic compressibilities were also calculated. A qualitativ e analysis of both of these functions revealed that structure disruptions a re more predominant in MMA +1-alcohol than in MMA +alkoxyethanols mixtures. The estimated relative associations are found to become less in MMA +alcoh ol mixtures than in pure alcohols. The solvation numbers derived from the i sentropic compressibility of the mixtures, considering MMA as a solvent, sh owed that structure malting interactions are also present in MMA +alkoxyeth anols in addition to the structure disruptions.
