ABSTRACT
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.
