“…One is between water and n-butanol, and the other one is between LABE and water, as depicted in Table 4. Stockhardt et al 22 and Hill et al 23 provided the VLE and LLE experimental data of H 2 O/n-BuOH system. The comparison of the above experimental data and Aspen predicted phase equilibrium at 1 bar can be seen in Figure 1.…”

This work presents the conceptual process design and the associated control strategies for the manufacture of nbutyl levulinate, which can be a suitable fuel additive, because of its high octane number, high oxygen content, and low water solubility. A reactive distillation column is used to avoid problems of separation and equilibrium reaction in the conventional esterification process. Both the thermodynamic properties and the kinetic data are compiled from open literatures. Sensitivities of several key design variables, including the feed ratio of raw materials and operating pressure of the reactive distillation column, to the economic manufacturing of n-butyl levulinate are investigated. The optimal steady-state design is found through total annual cost analysis, using iterative optimization procedure. Two feasible control structures are presented for this reactive distillation process. A series of simulations shows that both of the control strategies can reject throughput disturbances quite well, but can only achieve ordinary control performance for handling the feed composition disturbances.

“…The data trend indicates solubility of water in butanol increases with temperature. Hill and Malisoff (1926) showed solubility data from a lower temperature to a higher temperature which were consistent and these data were taken for our final selection. Many references in DECHEMA (Gmehling and Menke, 1994) showed a decline of solubility of butanol in water with temperature; however, one source (Lesteva et al's data reported in Sorensen and Arlt, 1979) showed reverse behavior.…”

This is an extended research of the paper conducted to obtain a universal set of interaction parameters of the model NRTL over the temperature range 10 -100 °C for hexanebutanol-water system; meaning for binary pairs hexane-butanol, butanol-water and hexane-water; and for ternary system hexane-butanol-water. Thorough investigations of data selections for all binary pairs (Vapor-Liquid Equilibrium (VLE), Liquid-Liquid Equilibrium (LLE)), infinite dilution activity coefficient (γ ∞ ), infinite dilution distribution coefficient (D sw ), excess enthalpy (H E ), and for ternary system (LLE of hexane-butanol-water) were carried out. Finally quadratic temperature dependent interaction parameters were estimated regressing all the mentioned data and in each case calculated results were compared with literature values. The comparisons showed an overall percentage of error within 15% for the mentioned phase equilibrium calculations.

“…The discussion of our data requires some knowledge of water-phenol mixtures with and without added salt. Mixtures of water and phenol have been avidly studied over the last century and a wealth of experimental data is available both for bulk ((76, 77) and further references therein, (78)) and interfacial properties (although only at the air-solution interface ((79, 80) and further references therein). At room temperature water and phenol are only partially miscible (9% phenol in water and 29% water in phenol in weight percent) (78).…”

We study DNA adsorption and renaturation in a water-phenol two-phase system, with or without shaking. In very dilute solutions, single-stranded DNA is adsorbed at the interface in a salt-dependent manner. At high salt concentrations the adsorption is irreversible. The adsorption of the single-stranded DNA is specific to phenol and relies on stacking and hydrogen bonding. We establish the interfacial nature of a DNA renaturation at a high salt concentration. In the absence of shaking, this reaction involves an efficient surface diffusion of the single-stranded DNA chains. In the presence of a vigorous shaking, the bimolecular rate of the reaction exceeds the Smoluchowski limit for a three-dimensional diffusion-
