Liquid densities, viscosities, orthobaric heat capacities, surface tensions, thermal conductivities, and saturated vapor pressures were measured for samples of mole fraction purity of 99.98 % HMCTS, OMCTS, and DMCPS over wide temperature ranges, by using Anton Paar densimeter, Hoeppler viscosimeter, Perkin-Elmer DSC 1B, modified bubble method, "hot wire" technique, and comparative ebulliometry, respectively. The experimental data were correlated and deviations or, for vapor pressure data, overall measures of data reproducibility are given.

The saturated vapor pressures were measured for samples, of mole fraction purity of 99.98 %, of 1-methyl-2-pyrrolidone (NMP), 1-methyl-azepan-2-one (N-methylcaprolactam), and 1,2-epoxy-3-chloropropane (epichlorohydrin) over wide temperature ranges by comparative ebulliometry. Measurements were made over the temperature range of (380.73 to 475.72) K for 1-methyl-2-pyrrolidone, (402.95 to 510.60) K for N-methylcaprolactam, and (315.67 to 388.29) K for epichlorohydrin, respectively. The experimental data were correlated, and overall measures of data reproducibility are given. The results are compared with literature data.

The saturated vapor pressures were measured for samples of mole fraction purity of 99.98 % hexanal, 2-methylcyclohexane, and 2-cyclohexen-1-one over wide temperature ranges by comparative ebulliometry. Measurements were made over the temperature range of (322.27 to 402.17) K for hexanal, (338.76 to 436.94) K for 2-methylcyclohexanone, and (350.40 to 445.00) K for 2-cyclohexen-1-one, respectively. The experimental data were correlated, and overall measures of data reproducibility are given. The results are compared with literature data.
