New preparation method of 2-ethylbutyric acid

The invention provides a new preparation method of 2-ethylbutyric acid. The preparation method includes the steps of: performing a reaction to propyl aldehyde and ethyl magnesium halide to prepare 3-pentanol; preparing 3-halogenated pentane from the 3-pentanol; preparing a Grignard reagent from the 3-halogenated pentane, and performing a reaction with CO2 to prepare the 2-ethylbutyric acid. The synthesis route is represented as follows. The method employs easy-to-obtained raw materials and is high in atom economy and low in industrial cost, thereby avoiding some defects in conventional methods.
