Modelling the diffusion coefficient D for solvents other than water

3 Modelling the diffusion coefficient D for solvents other than water 

Estimates of tjs were from the exponential model given above there were insufficient viscosity values at the necessary temperatures to allow the use of measured values. Modelling D did not provide reliable models, just as described in the case of water as solvent, and is not reported further. 

Under this approach the model becomes, for a particular solvent  

Least squares regression gives the results shown in Table 15.3. For methanol and ethanol the model gives imprecise estimates of b and n respectively.
