Wide-range reference temperature-and-density based equations for the thermal conductivity of ethene and propene are given. These equations are based upon a body of critically assessed data, acquired partially using the transient hot wire method. The ethene correlation is valid from 110 to 680 K and up to 200 MPa with a maximum uncertainty of 5%. The propene correlation from 180 to 625 K at pressures up to 50 MPa, with an uncertainty of 5%....
