“…To find the optimal solution, the use of an optimization algorithm is required. In this work, a hybrid optimization algorithm combining global optimization and local search (Balland et al, 2000;Mouhab et al, 2008), is used: concrete optimization algorithms as well as the corresponding Matlab functions are shown in Table 2.1. Local search Interior-point algorithm c fmincon a The systematic model-development strategy is implemented as software using MATLAB R2014a.…”

“…Meanwhile, macroscopic kinetics includes not only chemical kinetics but also the mass transfer between different phases in a heterogeneous reaction medium and, thus, is more practically applicable [1]. There are several commercially highly important reactions that are conducted in a heterogeneous medium, such as sulfonations, saponifications [2][3][4], esterifications [5,6], and others. A widely applied method for syntheses of multiphase reactions including catalysts is phase transfer catalysis [7][8][9][10].…”

The reaction kinetics of ethyl benzoate saponification with sodium hydroxide in a heterogeneous reaction medium was investigated. The rate of reaction in a heterogeneous liquid-liquid system incorporates a chemical kinetics term as well as the mass transfer between both phases. The reaction was carried out in a reaction calorimeter and the overall reaction rate was determined from the obtained thermal profiles. The mass transfer parameters were calculated numerically, taking into account those reaction rate constants determined in our previous study, where the above-mentioned reaction was conducted in a homogeneous reaction medium. The dependence of the mass transfer parameters and reaction rates on different heterogeneity stages and temperatures is described.

The reaction was catalyzed by strong acidic cation-exchange resin Amberlite IR-120 in H+ form. Four process parameters, including reaction temperature (J), sucrose mass concentration (gS), catalyst mass concentration (gC) and the rotational frequency of the stirrer (fm) at four levels were considered in this study. Relative contributions of the proposed influencing process parameters on hydrolysis time were estimated by analysis of the variance (ANOVA). The results showed that J had a substantial effect on the reaction time (78,3 %), the fm and gC had a smaller ones (7,9 % and 6,4 %, respectively), meanwhile the remain fraction to 100 % represents error (7,4 %). The optimum conditions, where the time required for complete sucrose hydrolysis would be the shortest, are: J= 79 �C, gC = 180 g/L, gS = 50 g/L and fm = 180 min�1. Although the presented results refer strictly to the selected case study and are specific within the observed ranges of selected process parameters, the proposed procedure shows their potential usage in general process design.
