chemical properties | colorless liquid. The boiling point is 65.5 ℃, the relative density is 0.932(18/4 ℃), and the refractive index is 1.4255(18 ℃). Soluble in ethanol and ether, insoluble in water. |
uses | are used as intermediates and solvents in organic synthesis. |
production method | 3-methyl -2-furan carboxylic acid is added to dry quinoline, and copper powder is added as catalyst. When heated to about 250 ℃, quinoline is in a boiling state and the reaction escapes carbon dioxide. After the reaction, distillation is carried out to obtain 3-methylfuran with a yield of about 85%. |
