Thermodiffusion separation of the binary mixtures of argon 
with an ethanol, n-propanol, and iso-propanol vapor and the binary 
mixtures of ethanol with an n-propanol and iso-propanol vapor has 
been measured in the temperature range 331-347 K by the two-flask 
method and the thermodiffusion factor has been determined. The experimental 
values of the thermodiffusion factor have been compared to the results 
of calculation according to the Chapman-Enskog theory.
