Abstract

The viscosity (η) and the density of 3-methylpentane (3MP),2,3-dimethylpentane (2,3DMP), methylcyclohexane (MCH), methylcyclopentane (MCP), and of the 1:1 mixtures MCH/MCP and 3MP/Isopentane were measured from 293 down to either the freezing point or to the temperature at which η ≈10⁶ mPa s.For the glass-forming solvents 3MP, 2.3DMP, MCH/MCP, and 3MP/Isopentane η(Τ) can be represented by the sum of two Arrhenius terms and one Vogel-Tammann-Fulcher term: η(T)≈A₁ exp(E₁/RT)+ A₂ exp(E₂/RT) + A₃ exp[E₃/R(T-T₀] For the smaller viscosity ranges of the two crystallizing alkanes MCH and MCP, two Arrhenius terms are sufficient for the description of η(Τ).
