AI Technical Summary
In the existing tea synone synthesis method, the process is complicated and the reaction yield is low when oxidized by β-isophorone, while the catalyst preparation is complex and costly when oxidized by α-isophorone.
The method of synthesizing tea ketone by one-step method, using ethylene glycol as a reaction aid, and a cyclic ether intermediate product was generated under concentrated sulfuric acid conditions, destroying the conjugated double bond structure of α-isophorone, and using tert-butyl hydrogen peroxide solution as an oxidant, the tea ketone was obtained by one-step method.
The synthesis of tea ketone with simple operation, high conversion rate and high selectivity is achieved, with a product yield of 97-99%, avoiding the complex process and high costs in traditional methods.
