| titleOfInvention | Method for the preparation of 5-chloro-pentan-2-one |
| abstract | It was an object of the invention to develop a simple and environmentally friendly process for the preparation of 5-chloropentanone-2, starting from a ketal of a levulinic acid ester, its hydrogenation and subsequent reaction with hydrochloric acid.n n n The solution is that the ketal of the levulinic acid ester is first purified by distillation, the hydrogenation catalysts for the ketal are made alkaline and the 3- (2-methyl-1,3-dioxolan-2-yl) propane-1- ol is reacted with hydrochloric acid to form 5-chloropentanone-2.n n n Use as a pharmaceutical intermediate and for the production of cyclopropyl methyl ketone. |
