Bromo-6 naphtol-2 - Reference Information
| chemical properties | white needle crystal. Melting point 127-128 ℃, boiling point 200-205 ℃(0.267kPa), soluble in benzene and ethanol. |
| use | dye intermediate. Organic synthetic raw materials. Pharmaceutical intermediates, liquid crystal raw materials. Organic synthesis and fuel intermediates are also used as raw materials for insecticidal and sterilizer. |
| production method | is obtained by bromination and reduction of 2-naphthol. Add 2-naphthol and glacial acetic acid to the reaction pot, and then add the solution prepared by bromine and acetic acid. Add bromine, add water and heat to boiling, then cool to 100 ℃, add moss-like tin in batches, boil for 3 hours after adding, add to an appropriate amount of cold water under stirring to precipitate 6-bromo-2-naphthol, wash with water, filter, and dry at 100 ℃ to obtain crude products. The finished product is obtained by vacuum distillation and recrystallization. |
