METHOD FOR RECYCLING DERIVATIVES OF STYRENE Russian patent published in 2017 - IPC C07C5/03 C07C5/05 C07C29/17 C07C67/303 C07C13/47 C07C33/20 B82B3/00 B01J23/755

Abstract RU 2619590 C1

FIELD: chemistry.

SUBSTANCE: method consists in the reduction of styrene derivatives with molecular hydrogen in the presence of nickel nanoparticles under heating and is characterized in that nickel nanoparticles immobilized on a zeolite are used as the catalyst, the reactants are fed directly to the catalyst by two streams, the first of which is hydrogen supplied at a flow rate 420-710 l/(kg_catH), the second - the styrene derivative, supplied at a flow rate of 0.55 l/(kg_catH), and the reaction is carried out at a temperature of 190-260°C.

EFFECT: simplification of the method for reducing styrene derivatives and reducing the reaction time.
