Abstract

A gas-dissolving device was designed and connected to the falling-body viscometer

which was used to determine the viscosities of liquids in our lab before. The equipment can be used to determine the gas composition

the densities and viscosities of the solution at the same time. The densities and viscosities of [bmim

]

[PF

]

+ CO

binary system were determined in the temperature range of 313.2 to 413.2 K and pressure range of 5.0 to 25.0 MPa by the equipment. Then the viscosities of [bmim

]

[PF

]

+ CO

binary system at constant temperature

constant pressure

and different temperature and pressure were correlated

respectively. For the correlation at different temperature and different pressure for different concentration mixtures the average relative deviation ARD is 0.037.
