Diffusivities of some organic amines in alcohols
- 16 Downloads
Experimental data on diffusivities involving organic amines diffusing in alcohols have been reported using the diaphragm cell technique. Experimental values have been compared with the predicted values by the generalized correlation proposed by Laddha and Smith.
