ЧТО ОЗНАЧАЕТ СЛОВО HYDROPEROXIDE
Органический пероксид
Органические пероксиды представляют собой органические соединения, содержащие пероксидную функциональную группу. Если R 'представляет собой водород, это соединение называют органическим гидропероксидом. Перестройки имеют общую структуру RCOOR. О-O-связь легко ломается и образует свободные радикалы формы RO ·. Таким образом, органические пероксиды полезны в качестве инициаторов для некоторых типов полимеризации, таких как эпоксидные смолы, используемые в стеклопластиках. MEKP и бензоилпероксид обычно используются для этой цели. Однако такое же свойство также означает, что органические пероксиды могут либо преднамеренно, либо непреднамеренно инициировать взрывную полимеризацию в материалах с ненасыщенными химическими связями, и этот способ был использован во взрывчатых веществах. Органические пероксиды, подобно их неорганическим аналогам, являются мощными отбеливающими агентами. Мостиковая перекисная группа в аскаридоле.
