“…The results were slightly different from the studies by Komoń et al (2013), in which the estimated enthalpies of reaction were 43.8 kJ/ mol (K a ) and 46.1 kJ/mol (K x ), respectively. The estimated enthalpy of reaction obtained by Fomin et al (1991) was remained at 70.1-72.3 kJ/mol for temperature in the range of 363-383 K.…”

“…Among the commercial catalysts, the organic resin was preferred compared to solid oxides due to the higher conversion attained (Bianchi et al, 2003;Peters et al, 2006;Fernandes et al, 2012;Chen et al, 1999;Komoń et al, 2013).…”

“…where γ i is the liquid activity coefficient for component i and it can be calculated using UNIFAC group contribution method (Komoń et al, 2013;Peykova et al, 2012). The UNIFAC model splits up the activity coefficient for each species in the system into two components; a combinatorial, γ c i and a residual component, γ r i as shown in Eq.…”

The heterogeneous esterification reaction of acrylic acid with hexanol over three different cation-exchange resins, Amberlyst 131, Amberlyst 15, and Dowex 50Wx-400, was investigated. Surface area, pore volume, average pore diameter, and acid capacity analyses were carried out for these three catalysts. Amberlyst 131 gave the highest conversion, and therefore, further experiments were performed catalyzed by Amberlyst 131. The absence of external and internal mass transfer resistances was investigated for the esterification of acrylic acid with hexanol. Experiments showed that the reaction is controlled by chemical step rather than external and internal mass transfer steps. The effects of temperature, catalyst loading, and alcohol to acid molar ratio on the conversion of acrylic acid were determined. The activation energy and kinetic and adsorption constants were determined according to the LangmuirHinshelwood-Hougen-Watson mechanism. C

The alkoxylation of camphene with 2-methyl-1,3-propanediol was studied using anhydrous macroporous and strong acid cation exchange resins as catalysts. The effects of various parameters, such as catalyst type, solvent, molar ratio of reactants, reaction temperature, and reusability of catalysts, were investigated in a 250 mL stirred tank reactor to optimize the reaction conditions. The UNIFAC group contribution method was used to correct liquid nonideality, giving the thermodynamic equilibrium constant at 333-370 K. The enthalpy changes calculated by three different methods (Gaussian 03, constant, and a function of temperature) were compared. The value (274.6 6 3.3 kJ/mol) calculated by the last method was closer to the theoretical value (275.73 kJ/mol) than that given by the second method (230.2 61.2 kJ/mol). A Langmuir-Hinshelwood-Hougen-Watson model based on activity was used to fit experimental data and the activation energy was 29.14 kJ/mol. The optimized reaction conditions were also verified in a 5 L reaction kettle.
