Description

technical field

[0001] The invention relates to a synthetic method of solanum aldehyde, which belongs to the technical field of organic chemistry. Background technique

[0002] Solanal (2-phenylpropanal) is a precious spice and an important chemical raw material, widely used in spices, medicine, dyes and pesticides and other industries. The industrial production method of Solanum aldehyde is to use acetophenone and ethyl monochloroacetate as raw materials, and synthesize it according to the Darzens method. Acetophenone and ethyl monochloroacetate are prepared under the action of a strong base to produce methyl phenyl glycidic acid ester. The ester is saponified, neutralized, and hydrolyzed into an acid, and then the acid is heated and decomposed to obtain solanaldehyde. This method operation is more complicated, and productive rate and product purity are not high. In order to seek cheaper artificial synthesis routes, many people are engaged in research in this area.
