Reaction orders for the reactants (butanoic acid and glycerol) were determined. They are close to 1.It was shown that the reaction order with respect to the catalyst - orthophosphoric acid - in regions where its concentration is above 0.1 mol/l is equal to zero. The estimated value of activation energy is 51.9± 8.0 kJ/mol. The results of the experiment can be used to create an industrial technological process for the synthesis of glycerol tributyrate. This compound can be used as an alternative non-phthalate plasticizer for articles made of PVC. The obtained kinetic model was validated on glycerol-containing waste of the biodiesel synthesis from renewable raw materials. The recycling of the by-product in the biofuel production with obtaining plasticizing compositions for the polymer industry can be developed on the basis of the studies.</p></abstract><trans-abstract xml:lang="ru"><p>В работе на модельных системах исследована кинетика каталитической этерификации глицерина бутановой кислотой. Определены порядки реакции по реагентам (бутановая кислота, глицерин), которые близки к единице. Показано что в областях концентрации катализатора более 0.1 моль/л, порядок по нему равен нулю. Оценено значение наблюдаемой энергии активации, которое составило 51.9±8.0 кДж/моль. Результаты эксперимента позволяют рекомендовать условия для создания технологии промышленной реализации процесса синтеза трибутирата глицерина, который может быть использован в качестве альтернативной нефталатной пластифицирующей композиции для изделий из ПВХ. Полученная кинетическая модель проверена на глицеринсодержащих отходах процесса синтеза биодизеля из возобновляемого сырья, что позволяет предложить способ утилизации побочных продуктов при производстве биотоплива с получением технически востребованного продукта для полимерной промышленности с высокой добавленной стоимостью.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глицерин</kwd><kwd>этерификация</kwd><kwd>бутановая кислота</kwd><kwd>кинетические исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glycerol</kwd><kwd>etherification</kwd><kwd>butanoic acid</kwd><kwd>kinetic study</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Thompson J.C., He B.B.
