| 8-Hydroxyquinaldine Usage And Synthesis |
| Chemical Properties | beige to brown crystalline powder. Soluble in hot alcohol, ether and benzene, insoluble in water. Can volatilize with water vapor and sublimate at 100℃. With phenol odor. |
| Uses | 8-Hydroxyquinaldine is mainly used as metal ion extractant and metal ion determination, also used in the synthesis of dyes and pigments and the preparation of pharmaceutical intermediates. |
| Preparation | 8-hydroxyquinaldine is obtained from the reaction of 2-aminophenol with crotonaldehyde. Mix 2-aminophenol and 2-Nitrophenol homogeneously and add hydrochloric acid. Add crotonaldehyde under stirring. Heat for 6h and leave overnight. Distill the reacted o-nitrophenol by water distillation, and add sodium hydroxide solution to the residual solution to make it weakly basic. Then add powdered carbonyls for saturation, and distill 8-Hydroxyquinaldine by water distillation, and then distill the crude product under reduced pressure and recrystallize it with ethanol to obtain 8-hydroxyquinaldine. |
| Definition | ChEBI: 2-Methylquinolin-8-ol is a hydroxyquinoline. |
| Synthesis Reference(s) | Tetrahedron, 52, p. 2937, 1996 DOI: 10.1016/0040-4020(95)01118-8 |
| General Description | 2-Methyl-8-quinolinol is a methyl substituted quinolinol derivative that shows fungicidal property. It can also undergo complexation with transition metal complexes. |
| Purification Methods | Crystallise the quinoline from EtOH or aqueous EtOH. Its solubility at 20o in H2O is 0.366g/L, and in CHCl3 it is 466g/L. It complexes with many metals. [Beilstein 21 H 106, 21 III/IV 2132.] |
