摘要
Static viscosity measurements of two mixtures of 3-bromopentane in 5-methylpentane are presented in the temperature range from 94 to 112 K and over a range of viscosities from 3 x 10(7) to 280 Pas. The data are fitted to the Vogel-Fulcher-Tamman equation. Estimates of the glass transition temperatures for these mixtures based on the reference viscosity of 1 x 10(12) Pas 90.1 and 98.8 K for 0.500 mole fraction and 0.750 mole fraction of 3-bromopentane in 3-methylpentane, respectively. Additionally, viscosity measurements on pure 3-methylpentane, previously reported, have been extended to higher temperatures. These viscosity values and those measured in this laboratory on 3-bromopentane, along with estimates of their glass transition temperatures, are also presented for comparison purposes.
