ABSTRACT

Critical temperature, critical pressure, and vapor pressure measurements have been performed on 15 compounds by a flow method with ultralow residence times. These compounds are c-butyrolactone, di(propylene glycol), 1,3-butanediol, N-methyldiethanolamine, 4-formylmorpholine, 1,2-epoxy-2-methylpropane, diethyl oxalate, n-butyl acrylate, 2-(2-aminoethoxy)ethanol, tert-butyl acetate, 1,1-ethanediol diacetate, p-diisopropylbenzene, dimethyl disulfide, oxazole, and phenyl isocyanate. Accurate vapor pressure data are also included for di-n-butyl disulfide and sulfolane, but these compounds proved too unstable to directly determine the critical constants using this apparatus.
