摘要

Azeotrope-like compositions are disclosed. The azeotrope-like compositions are mixtures of (a) Z-1,1,1,4,4,4-hexafluoro-2-butene; and (b) E-1-chloro-2,3,3,3-tetrafluoropropene. Also disclosed are processes for using such azeotrope-like compositions for preparing a thermoplastic or thermoset foam, for producing refrigeration, for producing an aerosol product and for extinguishing and suppressing a fire; and as blowing agents, solvents, heat transfer media and dielectrics.
