METHOD OF RESTORING DERIVATIVES OF STYRENE Russian patent published in 2017 - IPC C07C29/17 C07C33/18 C07C67/303 C07C69/612 C07C5/03 C07C15/24 

FIELD: chemistry.

SUBSTANCE: method consists of reduction of styrene derivatives with molecular hydrogen in the presence of nickel nanoparticles upon heating. Nickel nanoparticles immobilized on an ion-exchange resin 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 of 2400 l/(kg_Cat·h), the second - unsaturated bicyclic compound, supplied at a flow rate of 7.2 l/(kg_Cat·h), and the reaction is carried out at a temperature of 130°C.

EFFECT: simplification of the process of styrene derivatives reduction and the production of the desired products with a high yield in a shorter reaction time.
