introduction | 2,5-dimethoxyacetophenone is the representative substance of such compounds. it is a transparent yellow liquid with a density of 1.139 g/ml at 25 c (lit.) and a boiling point of 155-158 c 11mm Hg(lit.). |
preparation | weigh 5g of 2,5-dimethoxybenzene sample in a 100 ml three-mouth flask, dissolve with 10 ml of carbon tetrachloride, add 5. 5g of anhydrous aluminum trichloride, and stir with magnets; Under the condition of ice bath , 3.5 ml of acetyl chloride (diluted with 10 ml of carbon tetrachloride) is added dropwise at a rate of 30 drops per minute. The resulting hydrogen chloride is introduced into the sodium hydroxide absorption cell. The reaction time is 1. 5 hours. Then at room temperature, react for another 5 hours. The reaction mixture is washed with hydrochloric acid ice water mixture, ethyl acetate is extracted twice, the organic phase of the extract is combined, magnesium sulfate is dried, and left overnight . Rotary evaporation removes ethyl acetate. Column separation, ethyl acetate: petroleum ether = 1:5 as eluent. The target compound 2, 5-dimethoxyacetophenone was obtained. |
