Critical temperature, critical pressure, and vapor pressure measurements have been performed on 15 compoundsby a flow method with ultralow residence times. These compounds are

-butyrolactone, di(propylene glycol),1,3-butanediol,
N-methyldiethanolamine, 4-formylmorpholine, 1,2-epoxy-2-methylpropane, diethyl oxalate,
n-butylacrylate, 2-(2-aminoethoxy)ethanol,
tert-butyl acetate, 1,1-ethanediol diacetate,
p-diisopropylbenzene, dimethyldisulfide, oxazole, and phenyl isocyanate. Accurate vapor pressure data are also included for di-
n-butyl disulfideand sulfolane, but these compounds proved too unstable to directly determine the critical constants using thisapparatus.
