SIMULTANEOUS CHLOROFORM AND TERTIARY ALKYL CHLORIDE PRODUCTION PROCESS Russian patent published in 2008 - IPC C07C19/04 C07C19/01 C07C17/354

Abstract RU 2322433 C1

FIELD: industrial organic synthesis.

SUBSTANCE: according to invention, carbon tetrachloride and an alkane are dissolved in chlorobenzene and then are added cupric chloride and complexion agent containing quaternary ammonium cation selected from selected from R₄N⁺Cl^- and (R¹)₃(R²)N⁺Cl^-, wherein R represents hexyl, heptyl, or octyl, R¹ butyl or octyl, and R² is benzyl, at cation-to-copper molar ratio (10-5):1 and copper concentration 0.95-1.3 g/L to form anionic cupric chloride complex, which is used as catalyst in liquid-phase hydrogenation of carbon tetrachloride with isoalkane at 130-160°C for 2 to 11 h to form chloroform and isoalkane chlorinated in tertiary position.

EFFECT: enabled repetitive us of catalyst and increased selectivity of reaction.
