✦ Synopsis
We report measuremenl ol Ihe vapour prespures ol CCI2F 2 and CCIFa in Ihe lemperalure ranges 1 72-293 K and 188-273 K, respecHvely. The esl=mated uncerlamhes are 0.2 kPa, max=mum, Ior pressure and 0.001 K Ior lemperalure. In addtl0on, Ihe mosl accurale vapourpressure measuremenls avadable for CClaF, CCI2F 2 and CCIF u were represenled by a Wagner-lype equal=on Irom almosl Iheir Ir;ple po,nts Io Ihe,r cril~cal points. These equal=ons are shown Io prowde adequale represenlalions ol Ihe selecled exper~menlal resulls over Ihe enl,re hquid range. The corresponding values ol Ihe Wagner paramelurs are reported.
