“…The catalytic reaction of the synthesis of benzylalkyl esters occurs by intermolecular dehydration of benzyl and n-butyl alcohols with the formation of three esters: target benzylbutyl and side dibenzyl, dibutyl. The kinetic model of the catalytic reaction of the synthesis of benzylalkyl esters is presented in [1]. The model represents a system of differential equations.…”

The result obtained in the course of solving optimization problems is relevant for use in industrial and laboratory processes. Multi-criteria optimization involves optimizing two or more conflicting objective functions. Materials and methods. On the basis of the kinetic model of the catalytic reaction of the synthesis of benzylalkyl esters, the task of multi-criteria optimization is set taking into account the variable parameters: temperature, molar ratio of reagents and the time of carrying out, which have limitations. The use of the methods of «ideal» point and lexicographic ordering is justified.Results. An algorithm for solving the multi-criteria optimization problem has been developed. Using the kinetic model of the synthesis of benzylalkyl esters, the problem of MKO of the conditions of conducting was solved and optimal values of the variable parameters of the system were obtained, at which the output of the target product was maximized and the by-products of the chemical process were minimized. Discussion and conclusions. Multi-criteria optimization of this process will make it possible to give technological recommendations for the industrial implementation of the process with maximum output of target products and minimum content of by-products. The paper presents two methods for solving the problem, since in order to apply the results obtained in practice, the recommendations of the decision-maker must be taken into account.
