5-methylquinoline use and synthesis

Chemical Properties A colorless or light yellow oily liquid. The melting point of 19 ° C, the boiling point of 262.7 ° C, 129 ° C (2.0 kPa), the relative density of 1.0830 (20 / 4 ° C), the refractive index of 1.6219. It is miscible with ethanol and ether, soluble in benzene, and slightly soluble in water.

Use For the synthesis of photosensitizing dyes.

Production method is prepared by reacting m-amino-p-toluonitrile with glycerin. The m-amino-p-toluonitrile, 70% sulfuric acid, glycerin and sodium m-nitrobenzenesulfonate were heated under reflux for 5 h with stirring, and the reaction temperature was lowered from 148 ° C to 137 ° C. After cooling, dilute with water, add concentrated ammonia to make it alkaline, add acetic acid, and acidify to pH 4-5. Concentration, cooling and precipitation of 5-methyl-8-carboxyquinoline crystals. Then, a silver salt is added for distillation under reduced pressure to obtain 5-methylquinoline. The yield was 10%.
