synthetic route
An industrially feasible synthesis method is as follows:
Add a portion of 1-chlorobutane to a solvent containing magnesium metal and heat to initiate the reaction.
Add the remaining 1-chlorobutane dropwise within 3-10 minutes and maintain reflux.
After the dropwise addition is complete, continue to reflux until the reaction is complete.
Add the reaction mixture dropwise into a container containing dry ice within 10-30 minutes, and then let it rise naturally to room temperature.
Add MgHSO ?, stir and filter. The filtrate is acidified and purified to obtain valeric acid.
This method has a wide range of raw material sources, low cost, and is suitable for industrial production.
