Viscosity and Density of 2-Methyltetrahydrofuran as a Function of Temperature.

摘要

The viccosity and density of 2-methyltetrahydorfuran have been determined from -60to 23exp 0 C. Viscosity measurements were made using a Ubbelohde viscometer and the density measurements were made using a pycnometer of our own design. The data are represented by the following formulae:ln eta = -3.635 + 896.8T exp -1and d = 1.138 - 9.56 x 10exp -4 T,where eta is the viscosity in centipoise, d,the density in grams per cubic centimeter,and T,the temperature in exp 0 K. Previous literature data,which extend the viscosity into the glassy state,are included. 6figures, 4tables. (ERA citation 04:024112)
