摘要：

The melting point difference between a hydrogenated n-alkane and its deuterated counterpart is found to be dependent on the length of the n-alkane. The melting point difference increases in going to longer chains. For chains ranging in length from methane to polyethylene, the difference is to a good approximation linearly related to the melting point. The observed relation DELTA-T(m) = delta-T(m) can be accounted for on the basis of the principle of corresponding states. The value of delta obtained from a plot of DELTA-T(m) vs T(m) agrees well with the value of delta reported earlier from an analysis of vapor pressure data for CH4 and CD4.
