VAPOR PRESSURE STUDIES ON METAL CHELATES

Abstract

The vapor pressures of several metal chelates of acetylacetone, trifluoroacetylacetone and hexafluoroacetylacetone were measured in the temperature range 40 to 140 deg C by the effusion and isoteniscope methods. The results showed large differences from the literature values, where available, and a qualitative discussion is offered to illustrate the major sources of error in the experiments. A comparison between the experimental vapor pressure trends among the chelates and the observations made with regard to the order of elution of the chelates in gas chromatography showed that for the chelates of a given metal atom, the volatility increased with increasing fluorination of the ligand and the time for elution from the chromatographic column decreased.
