“…The major volatile organic contaminant both before and after distillation was ethyl trifluoroacetate. The normal boiling point of ethyl trifluoroacetate has been reported to be 61.6 °C (Macey, 1960) 1, was constructed to maximize the safety of the operator without compromising the integrity of the viscosity measurements. H + hfac is a corrosive material, harmful in both its liquid and gas phases (Lenga and Votoupal, 1996).…”

The viscosity and vapor pressure of the reactive chelating ligand, 1,1,1,5,5,5-hexafluoro-2,4-pentanedione (H+hfac) have been determined. The viscosity of liquid H+hfac was determined to be (1.39 ± 0.19) × 10-3 Pa·s at 24 °C and (8.35 ± 0.25) × 10-4 Pa·s at 35 °C. The vapor pressure of H+hfac was found to range from 4 kPa at 0 °C to 49.5 kPa at 57 °C. The viscosity was measured using a capillary tube viscometer, and the vapor pressure was measured using a mass transfer gas saturation apparatus. These methods were employed because conventional methodologies would have produced unreliable data due to the formation of the tetrol hydrate of H+hfac inside the apparatus and potentially exposed laboratory personnel to hazardous working conditions.

Vapour phase thermolysis at 485°C of methallyl acetate and the allyl esters of benzoic, phenylacetic and trifluoroacetic acid proceeds by radical mechanisms analogous to that proposed for allyl acetate1. Rates of primary allyl‐oxygen homolysis appear to depend only slightly on the nature of the acyl moiety. The induced radical decomposition proceeds mainly by addition to ester, followed by β‐elimination, polymerization being unimportant under the present experimental conditions. An explanation is offered for the fact that allyl(ic) esters of aromatic acids ‐ in contrast to those of aliphatic acids ‐ produce a substantial amount of carboxylic acid in addition to the main oxygen‐containing product, carbon dioxide.
