Process for the preparation of a cyclic ketone |
| abstract |
The present invention relates to a process for the preparation of a cyclic ketone from a dicarboxylic acid by decarboxylation and cyclization.n n n The preparation process of the invention is characterized in that the reaction is carried out in the presence of an effective amount of a neutral phosphate, condensed or not.n n n The invention relates more particularly to the preparation of cyclopentanone from adipic acid and 2,2-dimethyl cyclopentanone from 2,2-dimethyl adipic acid. |
