Abstract
Синтезовано ізопропілаурат з викорис-
танням як каталізатора суміші оксидів металів. Найвищу кон-
версію отримано за таких умов: 393 К, молярне співвідно-
шення ізопропанол:лауринова кислота 10:1, склад каталіза-
тора 33 % CuO, 33 % Ag2O і 33 % Al2O3, співвідношення
каталізатор/лауринова кислота становить 8 мас %, час
реакції 2 год. Показано, що оксиди каталізатора після
естерифікації не перетворюються в інші речовини.
This paper reports the synthesis of isopropyl laurate while using a mixture of metal oxides as a catalyst. The best conversion value was obtained in the following conditions: 393 K, isopropanol:lauric acid molar ratio is10:1, composition of the catalyst is 33 % CuO, 33%Ag2O and 33 % Al2O3, catalyst/lauric acid ratio is 8%(w/w), and reaction time 2 h. Isolation of the catalysts after esterification showed that the oxides were not converted into other materials.
