Viscosity of mixtures of indole containing 2-methylnaphthalene and isoquinoline under pressure
Chiaki Yokoyama, Jun Takei, Akibumi Kumagai
The liquid viscosities of the binary mixtures of indole containing 2-methylnaphthalene and isoquinoline were measured along five concentrations at 333.15 K and pressures up to 260 MPa or up to the freezing pressures of one of the constituent components in the mixtures. The measurements were carried out with a falling capillary viscometer, and they have a reproducibility of 1.4%. The experimental values could be fitted to the Doolittle equation within ±3.7%.
