5-Methylquinoline - Reference Information
| chemical properties | colorless or light yellow oily liquid. Melting point 19 ℃, boiling point 262.7 ℃,129 ℃(2.0kPa), relative density 1.0830(20/4 ℃), refractive index 1.6219. It is miscible with ethanol and ether, soluble in benzene, slightly soluble in water. |
| use | for the synthesis of photosensitive dyes. |
| production method | is prepared by reacting m-amino p-toluonitrile with glycerol. The reaction temperature was reduced from 148 ℃ to 137 ℃ by heating and refluxing m-amino p-toluene nitrile, 70% sulfuric acid, glycerol and sodium m-nitrobenzene sulfonate under stirring for 5h. After cooling, add water to dilute, add concentrated ammonia to make it alkaline, add acetic acid, and acidify to pH4-5. Concentrate and cool to precipitate 5-methyl-8-carboxyquinoline crystals. Then the silver salt was added for vacuum distillation to obtain 5-methylquinoline. 10% yield. |
