Part of the Physical Chemistry book series (volume 15B2)

Abstract

This chapter provides the diffusion coefficient of heptane in toluene at infinite dilution for various temperature and pressure conditions measured using interferometry, Gouy interferometry and Taylor dispersion technique.

Comment: the value of D01(2) seems rather unreliable, from binary interdiffusion data of [1985P2] a value of 2.21 is more appropriate
