Abstract

Изобретението се отнася до получаване на капролактам чрез разлагане на олигомери или полимери, които съдържат основно единица на периодичност -[-N(H)-(CH2)5-C(0)-]-, в присъствие на катализатор и привисока температура. Разлагането се осъществява в течна фаза в присъствие на хетерогенен катализатор и органичен разтворител.
