ABSTRACT
The vapor pressures of the acetonitrile + tetrabutylammonium bromide, water + tetrabutylammonium bromide, and acetonitrile + water + tetrabutylammonium bromide systems have been measured at five constant salt molalities [(0.200, 0.400, 0.600, 0.800, and 1.000) mol * kg-1]. These systems have been studied at (298.15 and 323.15) K with a modified Othmer still.
