Patent Number: 6,310,258

Title: Process for preparing 1,3-diketones

Abstract: The invention provides a process for preparing 1,3-diketones by rearrangement of the isomeric enol ester in a tube reactor comprising a heated portion and an unheated insulated portion which can optionally be provided with cooling means. The unheated portion of the reactor has a higher volume to surface ratio than the heated portion of the reactor. The reaction can be carried out adiabatically in the unheated portion of the reactor. The process and apparatus provide higher yields and selectivity to the 1,3-diketones.
