Physical Properties of HCFO-1233zd(E)

A new low global warming potential (GWP) fluid hydrochlorofluoroolefin trans-isomer of 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) has been developed in our laboratory. HCFO-1233zd(E) has a very short atmospheric lifetime of 26 days and a global warming potential (GWP) of less than 5 (Wong et al., http://www.honeywell-solsticelba.com. product-info/environmental-regulatory/#atmospheric-impact, 2012). This makes it an excellent environmentally friendly candidate for many applications including refrigeration, foam expansion agents, and as solvents. In this work we have presented our measurements of physical properties like the boiling point, critical temperature, vapor pressure, liquid density, and surface tension of HCFO-1233zd(E). We have also provided our calculated ideal gas heat capacity at constant pressure using quantum mechanical theory. Temperature-dependent properties are correlated with standard forms of equations and described in the paper.
