Viscosities of binary and ternary mixtures of polyaromatic hydrocarbons

Experimental measurements of the viscosities of the three binary-mixture combinations of the toluene/tetralin/1-methylnaphthalene system were performed over the entire concentration range for various temperatures ranging from 298 to 498 K. Viscosities were also determined for an equimolar mixture of the three components and for the binary naphthalene/tetralin system. Finally, the polar phenol/picoline mixture was found to have interesting associative properties. The viscosity data determined have an experimental uncertainty of 1.1%. The viscosity correlation of Mc Allister gave excellent representations of both binary and ternary data.
