| titleOfInvention | Process for preparing methyl heptenone |
| abstract | PROCESS FOR PREPARING METHYL HEPTENONE ABSTRACT OF THE DISCLOSURE A process is provided for preparing methyl heptenone from mesityl oxide or acetone or mixtures thereof in improved yield. Mesityl oxide is reacted with prenyl chloride to form a ketone mixture comprising mixed prenyl-substituted methyl pentenones, which is then separated from the residual reaction mixture by distillation, subjected to hydrolytic cracking with water in the presence of alkali at an elevated tempera-ture, and methyl heptenone recovered. The same ketone mixture is found as a by-product of the reaction of acetone with prenyl chloride in the presence of a catalyst to form methyl heptenone. This can therefore be subjected to the hydrolytic cracking reaction, thus increasing the amount of methyl heptenone produced. |
