Excess molar volumes and viscosities of binary mixtures of 4-methylpyridine with methanol, ethanol, propan-1-ol, propan-2-ol, butan-2-ol, and 2-methylpropan-2-ol at 298.15 K and atmospheric pressure

New experimental data on densities and viscosities for the systems 4-methylpyridine + methanol, + ethanol, + propan-1-ol, + propan-2-ol, + butan-2-ol, and + 2-methylpropan-2-ol are presented at 298.15 K and ambient pressure using a vibrating tube densimeter and an Ubbelohde viscometer. The results are discussed qualitatively in terms of the association of the mixture components caused by chainlike self-association of the alcohol molecules and cross-association between alcohol and 4-methylpyridine.
