Abstract
Изобретение касается способа плучения фенола окислительным цекарбоксилированием в жидкой фазе из соответствующей арилкарбоновой кислоты в присутствии растворенного Cu- содержащего катализатора, с последующим получением фенола через стадию гидролиза. Отличительная часть способа включает следующие стадии процесса:а) окисление катализатора при 120-190°С;в) восстановление и гидролиз при 225-270°С.
