SWIM has UTFSE and has fond nothing concerning this so please pardon if this has been discussed.
For the tetra trap, can one sub difluoroethane for tetrafluoroethane? can SWIM expect similiar results?

thanks in advance

No wonder, as the so-called 'tetra trap' procedure uses tetrachloroethylene rather than 1,1,1,2-tetrafluoroethane (boiling point -26°C) or 1,1-difluoroethane (boiling point -24.7°C).
