| titleOfInvention | A kind of synthetic method of cyclopropyl methyl ketone |
| abstract | The present invention relates to a synthetic method of cyclopropyl methyl ketone. The synthetic method comprises the following steps: 1) carrying out hydrogenation hydrolysis of 2-methylfuran in the presence of a hydrogenation catalyst, hydrogen and water in a one-pot method to prepare Obtain acetyl n-propanol; 2) step 1) the prepared acetyl n-propanol is carried out to hydrochloric acid chlorination to obtain 5-chloro-2-pentanone; 3) step 2) the prepared 5-chloro The crude product of ‑2‑pentanone undergoes a ring-closing reaction under alkaline conditions to obtain cyclopropylmethyl ketone. The synthesis method of cyclopropyl methyl ketone of the present invention uses 2-methyl furan as a raw material to prepare cyclopropyl methyl ketone through one-pot hydrogenation hydrolysis, hydrochloric acid chlorination reaction and ring closure reaction, and its process is simple and smooth , mild reaction conditions, suitable for industrial scale-up production; using 2-methylfuran as raw material, high atom economy, green and environmental protection, low raw material cost. |
