Uses & manufacturing
Applications
Uses2,2'-Biquinoline is used as a reagent for spectrophotometric determination of Cu and as an indicator for titration of organolithium reagents, giving yellow-green charge-transfer complexes.
General Description2,2′-Biquinoline is a white crystalline solid and it melts at 176°C. It is insoluble in water, but is soluble in ethyl, amyl and isoamyl alcohol, isoamyl acetate, dimethylformamide, acetic acid, acetonitrile and carbon tetrachloride.
Preparation methods
PreparationIn a 50 mL round-bottom flask, H2O (5.0 g), PEG-400 (1.0 g), and quinoline (1.0 g) were added sequentially. After stirring until homogeneous, W's Pd/C catalyst (0.1 g) was added and the reaction was carried out at 80°C for 20 h. The reaction solution was cooled and filtered. The Pd/C filter cake was washed with water and could be recycled and reused. The filtrate was extracted with ethyl acetate, the solvent was evaporated, concentrated, and crystals were precipitated to obtain the crude product. Recrystallization yielded 0.12 g of white 2,2'-biquinoline crystals, with a yield of 11.9% and a melting point of 196-197°C.
