Abstract The diffusion coefficients of several chlorinated hydrocarbons
in air were determined by using an Arnold cell. The chlorinated
hydrocarbons used were carbon tetrachloride, chloroform, 1, 2-
dichloroethane and dichloromethane. To determine the reliability
of the experimental method, diffusion coefficients were obtained
for benzene and ethanol. These were compared with diffusion coefficients
measured by other investigators.
An Arnold cell was used to determine the diffusion coefficients.
The diffusion tube was 0.373 inches in diameter, and the
diffusion path length varied between 4 and 13 centimeters.
The air flow rate across the top of the tube was maintained at 0.14
ft³ /min. for all runs except one series of runs with benzene. For
this one series of runs the flow rate was 0.095 ft³/min.
End effects due to turbulent eddies at the mouth of the tube
and the surface tension of the liquid were accounted for in the determination
of the diffusion coefficients.
