Description:

The paper gives results of a study of the retention characteristics of 13 heavier ethane-based and 8 ethene-based halocarbon fluids related to alternative refrigerant research as a function of temperature on a stationary phase consisting of a 5% (by mass) coating of a low molecular mass polymer of hexafluoropropylene epoxide on a graphitized carbon black adsorbent. Measurements were performed at 0, 20, 40, and 60 C for R-152; at 20, 40, 60, and 80 C for R-124; at 40, 60, 80, and 100 C for R-123a, R-152, and R-115I-1; at 60, 80, 100, and 120 C for R-132b, R-1130a, R-1121(cis), and R-1121(trans); at 80, 100, 120, and 140 C for R-113, R-123B1, R-141, R-1130(cis), and R-1130(trans); and at 100, 120, 140, and 160 C for R-113a, R-121, R-122, R-131, R-131a, R-1110, R-1111, and R-1120. Relative retentions as a function of temperature were calculated with respect to the retentions of tetrafluoromethane (R-14) and hexafluoroethane (R-116). Qualitative features of the data are examined and trends identified. In addition, the relative retention data were fitted to linear models for the purpose of predicting retention behavior of these compounds to facilitate chromatographic analysis.
