Abstract
Current methods for the oxidation of diolefins to furan compounds are mainly vapor phase processes which are generally characterized by low conversions and deficient selectivities. These disadvantages are due to the instability of the furan compounds at high temperatures in the presence of oxygen which leads to the formation of resinous compounds, carbonization and uncontrolled polymerization. The liquid phase process of the present invention eliminates these disadvantages by operating at moderate temperatures. Although several liquid phase processes are known for the production of furan compounds, they involve the use of oxygenates as starting materials. For example, u.s. Patent no. 3,932,468, issued january 13, 1976, and u.s. Pat. 3,996,248, issued december 7, 1976, refer to the transposition of butadiene monoxide, and u.s. Pat. No. 3,933,861, issued january 20, 1976, involves the reaction of an alkene and an alkene oxide to produce substituted furans. The two processes mentioned require oxygenated starting materials, while in the present invention, the furene compounds are obtained by the direct oxidation of the conjugated diolefin. Although japanese patent no. 77 77 049 discloses a process for the oxidation of butadiene to furan in an aqueous acidic medium, the process of the present invention is distinguished from this process in which the present process is conducted in an organic solvent medium in the that the catalyst and the furan products are more stable.
