| titleOfInvention | A kind of preparation method of methyl benzoylformate |
| abstract | The present invention relates to a kind of preparation method of methyl benzoylformate, by raw material 2, 2-dimethoxy-1-Phenyl ethyl ketone dissolves in organic solvent, under having or existing without free radical inhibitors, control certain temperature of reaction, appropriate chlorine and 2 are passed in 1-16 hour, 2-dimethoxy-1-Phenyl ethyl ketone reacts, single step reaction can obtain methyl benzoylformate, after reaction terminates, be cooled to less than 50 DEG C, wash with water, the organic phase separated, extremely neutral with the sodium bicarbonate aqueous solution washing of 5% again, the organic phase anhydrous sodium sulfate drying obtained, again through low-pressure distillation, obtain target product, content is more than 99%.Preparation process of the present invention completes through single step reaction, has low cost, easy to operate, route is short, yield is high, these advantages such as environmental friendliness. |
