METHOD OF PREPARING CATALYST FOR OBTAINING 3-ACETYLHEPTANE-2,6-DIONE AND METHOD OF OBTAINING 3-ACETYLHEPTANE-2,6-DIONE WITH APPLICATION OF OBTAINED CATALYST Russian patent published in 2013 - IPC B01J23/10 B01J37/08 B01J27/10 C07C49/04 C07C49/12 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to field of chemistry of ketones, in particular, to method of preparing catalyst for obtaining 3-acetylheptane-2,6-dione and to method of obtaining 3-acetylheptane-2,6-dione with application of obtained catalyst. Described are: method of preparing microdimensional catalyst for obtaining 3-acetylheptane-2,6-dione, which consists in dissolution of cerium chloride hydrate of formula CeCl₃×7H₂O in methyl alcohol with further removal of solvent by its evaporation for 1 hour at temperature 90°C and heating residue for 1.5 hour at temperature 150°C, and method of obtaining 3-acetylheptane-2,6-dione by interaction of acetylacetone with methylvinylketone in presence of obtained catalyst, process being carried out with molar ratio acetylacetone: methylvinylketone: catalyst in terms of CeCl₃×7H₂O equal 1:1:0.1-0.2.

EFFECT: increased output of 3-acetylheptane-2,6-dione to 76-87% due to application of obtained catalyst, nearly 3-fold reduction of amount of used catalyst, carrying out process of obtaining 3-acetylheptane-2,6-dione without solvent, as well as reduction of time of process carrying out, which makes process cheaper and reduces ecological load onto environment.
