4, 4-dimethoxy-2-butanone is an important fine chemical product, also known as acetaldehyde dimethanol, colorless or yellowish liquid at room temperature, which can be used in Chemicalbook to synthesize 2-chloro-3-amino-4-methylpyridine, 3-hydroxy-isovalerate dimethanol, 2-mercapto-4-methylpyrimidine and other pharmaceutical pesticide intermediates. preparation

In the laboratory, sodium metal was used as raw material and methanol as solvent, saturated methanol solution of sodium methanolate was prepared first, then acetone and methyl formate were added for Claisen ester condensation to obtain sodium butene Chemicalbook, and finally 4, 4-dimethoxy-2-butanone was synthesized by acetal reaction with methanol under the action of strong acid. The total yield was 73.19% and the purity was 98.7%.
