ETHYLBENZENE PRODUCTION PROCESS Russian patent published in 2006 - IPC C07C2/68 C07C5/02 

Abstract RU 2267476 C1

FIELD: industrial organic synthesis.

SUBSTANCE: alkylation of benzene with ethylene is carried out by supplying dried benzene feed, aluminum chloride-based catalytic complex, ethylene, recycled catalytic complex, and return benzene to alkylation reactor; separating resulting reaction medium from catalytic complex; neutralizing reaction medium with alkali; and flushing with water alkali; followed by rectification separation of reaction medium. According to invention, reaction components are preliminarily mixed in turbulent mode and fed into alkylation reactor also under turbulent conditions.

EFFECT: increased degree of benzene conversion.
