Critical point measurements consisting of critical temperatures and critical pressures have been performed on nine compounds by a flow method with ultralow residence times. These compounds along with their Chemical Abstract Service Registry Numbers (provided by the author) are bis(2-aminoethyl)amine (11140-0), 2-(2-aminoethylamino)ethanol (111-41-1), 1,4-butanediol (110-63-4), 2-(2-butoxyethoxy)ethyl acetate (124-17-4), 2-(2-ethoxyethoxy)ethyl acetate (112-15-2), 2-methyl-1,3-propanediol (2163-42-0), phenyl acetate (122-79-2), 1,3-propanediol (504-63-2), and propylene carbonate (108-32-7). Vapor pressure measurements are also included for these nine compounds.
