Abstract
Реакцією епіхлоргідрину з дитретинними ωгідроксиалкілпероксидами синтезовано нові епоксидовмісні
пероксиди. З’ясовано вплив умов проведення реакцій на вихід та
склад продуктів взаємодії. Реакціями отриманих пероксидовмісних гліцидилових етерів з 1,2;3,4-діізопропіліден-α-D-галактопіранозою або 6-гліцидил-1,2;3,4-діізопропіліден-α-D-галактопіранози з ω-гідроксиалкілпероксидами синтезовано нові
пероксидні похідні з дитретинними та первинно-третинними
пероксидними групами. Методом комплексного термічного
аналізу досліджено розклад синтезованих сполук та визначено
кінетичні параметри термолізу.
New epoxide-containing peroxides have been synthesized via the interaction between epichlorohydrin and ditertiary w-hydroxyalkyl peroxides. The effect of reaction conditions on both the yield and composition of the reaction products has been established. Through the reactions of either the synthesized epoxide-containing peroxides with 1,2;3,4-di-O-isopropylidene-a-D-galactopyranose or 6-O-glycidyl-1,2;3,4-di-O-isopropylidene-a-D-galactopyranose with the w-hydroxyalkyl peroxides, new peroxide derivatives with ditertiary and primarytertiary peroxide groups have been synthesized successfully. The decomposition of the developed substances has been studied by complex thermal analysis and the kinetic parameters of the thermolysis have been determined.
