Thick colorless yellow to yellow-brown liquid with a pungent odor. Insoluble in water, miscible with alcohol, ether, benzene and chloroform. 1-Bromonaphthalene is one of two isomeric bromonaphthalenes, the other being 2-bromonaphthalene.??
1-Bromonaphthalene is used in organic synthesis and refractometry of fats. It is used in the preparation of N-aryl imidazoles and diaryl ethers. It is used to determine the refractive index of crystals and the water content of alcohols. It is utilized in the preparation of glutathione peroxidase-like antioxidant activity of diaryl diselenides. Further, it serves as a solvent for the exfoliation and dispersion of hexabenzocoronene. In addition to this, it is used as a refrigerant and a solvent molecular weight substance.?? ??
1-Bromonaphthalene is synthesized by the reaction of naphthalene with bromine: C10H8+ Br2→ C10H7Br + HBr.Reaction: add carbon tetrachloride and naphthalene in the reaction pot, stirring and heating, and slowly add bromine at 45℃. After adding, keep the reaction at 70-80℃ for 3-4h. distillation to recover carbon tetrachloride, wash the reaction product, distill under reduced pressure, wash again, filter, dry and get the finished product.
?? ??
The vibrational spectra of 1-bromonaphthalene has been studied.Purification Methods
Purify 1-bromonaphthalene by passage through activated alumina, and three vacuum distillations. [Beilstein 5 H 547, 5 IV 1665.]1-??????? ?? ?? ? ???
