Baseci on the Eyring s absolute rate theory,a modified equation was proposed to es-timat,the infinite dilution diffusion coefficient from viscosity for binary liquid.

Gas-stripping method (GSM) is an efficient experimental method to measure infinite dilution activity coefficient (γ_i~∞), azeotropic data, relationship of activity coefficient (γ) and component (x) in dilute solution, as well as infinite dilute selectivity (S_(ij)~∞) of separating agents.

Computer NPT ensemble simulation of the chemical potentials and Henry constants for methane and benzene in infinite dilute aqueous solutions was carried out in terms of the thermodynamic integration with a coupling parameter, and the preferential sampling method.

The use of formula has calculated molar conductivity λ of YCl_(3 )in DMF and H_2O, The use of Kohlraush formula has made the diagram push outside and calculated the molar conductivity at infinite dilution λ_(0 )=233.

15 K to calculate the molar conductivity of DyCl3;secondly,Kohlrausch formula and Origin software were used to make the diagram of linear fitting,finally the diagram was pushed outside and the molar conductivity at infinite dilution(λ0 /(S·cm2 ·mol-1) of DyCl3 in isopropanol was calculated,and the influence of the temperature on λ0/(S·cm2·mol-1) of DyCl3 electrolyte solution was investigated.

Measurement of infinite dilution diffusion coefficients of small molecule solvents in nascent polyethylene particles by inverse gas chromatography;

Therefore by gas chromatography the infinite dilution diffusion coefficients of small molecule solvents in the silicon rubbers with different cross linker content were measured and how the cross linker content affects infinite dilution diffusion coefficient was studied.

Based on the mathematical model of Hadj-Romdhane and Danner describing the chromatographic process in a packed column, the infinite dilution diffusion coefficients of benzene, toluene and ethylbenzene in polyethylene membrane were measured in a temperature range of 341.
