4′-(Octyloxy)-4-cyanobiphenyl Use and Manufacturing

Methods of Manufacturing

General procedure: 4'-Hydroxybiphenyl-4-carbonitrile (1) (20.0 g, 0.1 mol), potassium carbonate (28.0 g, 0.2 mol) and DMF (600 mL) were placed in a 1000 mL flask and stirred. The corresponding alkylbromide (20.0 g for 1-bromohexane, 23.0 g for 1-bromo-octane, 0.12 mol) was added and the reaction mixture was heated at 120 °C for 48 h. The mixture was then cooled to room temperature and poured onto ice water (1000 mL) and left to stand overnight. The precipitated product was isolated by filtration and crystallized from ethanol.
