Extrapolation of the Orthorhombic n-Paraffin Melting Properties to Very Long Chain Lengths
Abstract
An analysis of the equation TM=T0 (n+a) / (n+b) is made in order to determine the convergence temperature T0 of the melting temperatures of the n-paraffins from C44 to C100. A good fit is obtained using T0=414.3°K, a=—1.5, and b=5.0. This value of T0 (414.3°K=141.1°C) has an estimated total uncertainty of ±2.4°K and is proposed as the correct value of the equilibrium melting temperature of polyethylene. It is shown that presently available data do not permit accurate extrapolation of the n-paraffin heats and entropies of fusion to the polymer limit.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
