1. An azeotrope-like composition consisting essentially of (a) trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze) and (b) 1,1-difluoroethane (“HFC-152a”), said HFC-152a being present in the azeotrope-like composition in a range of from about 50 wt % to less than 100 wt %, wherein said composition includes a minimum boiling azeotrope having a liquid composition component concentration equal to the vapor composition component concentration, whereby at a pressure of about 14.4 psia said azeotrope-like composition has a boiling point of −23° C.+1-2° C. |
