Abstract
Thermal diffusion measurements have been made on a series of binary mixtures of normal paraffin hydrocarbons with tetrachloroethane over a range of temperatures from 5‐55°C. The results are analyzed in terms of a previously published theory. The size of hole left by the hydrocarbon seems independent of chain length up to an eight or nine carbon chain. If the moving segment is assumed to be eight carbon atoms long, the size of hole left by the segment is independent of total chain length.
