Abstract

The rate of liquid-phase hydrogenation of monoalkylphenols without solvent and in the absence of rate control by hydrogen diffusion to the catalyst indicate that the alkylphenol reactivity and the selectivity depend on the position and size of the alkyl substituent, affecting the electronic state of the aromatic ring and the charge on the carbonyl carbon atom of the ketone intermediate.

Abstract

Изучена скорость жидкофазной гидрогенизации моноалкилфенолов в условиях, исключающих торможение реакции диффузией водорода к катализатору и в отсутствие растворителя. Показано, что реакционная способность алкилфенолов и селективность процесса зависят от положения и величины алкильного заместителя, влияющего на злекронное состояние ароматического коляца и величину заряда на атоме углерода карбонильной грпппы промежутогного кетона.
