Molecular diffusion in a ternary liquid system with the diffusing component dilute

Sorption enhanced reactive process for the synthesis of glycerol ethyl acetal

“…Instead, the effective diffusion coefficient of compound in a multicomponent mixture, D eff ;i , was determined by applying the Perkins and Geankoplis [43] mixing rule to the infinite dilution diffusion coefficients estimated by the Scheibel [44] equation and assuming a particle tortuosity value equal to the inverse of the particle porosity as reported by Wakao and Smith [45], while the film mass transfer coefficient was estimated based on correlation (9). …”

Degradation of the oxirane ring of epoxidized vegetable oils in liquid–liquid heterogeneous reaction systems

“…(20), new values of the Hatta number in the aqueous phase were obtained. As shown in Table 7, these values were between 32 and 283, which indicates that the reaction between the solvated acetic acid and the epoxide groups is in the fast regime in the polar phase, even though no sulfuric acid was added to the reacting media.…”

“…The diffusion coefficients in the multicomponent liquid mixtures were estimated using the simple, semi-empirical model of Perkins and Geankoplis based on a modified version of the Wilke and Chang equation [20]:…”

Continuous adiabatic industrial benzene nitration with mixed acid at a pilot plant scale

“…According to Chapman and Strachan [12] Eqs. (2) and (3), which are modifications of equations proposed by previous authors [13,3], can provide the diffusion coefficient of an aromatic compound in the mixed acid,…”
