ABSTRACT:
A process of removing solids from an aqueous redox catalyst system which solids are formed in the production of furan compounds from butadiene or a butadiene derivative by heating at 180.degree.-280.degree. C. in the presence of sufficient cupric ion or oxygen to oxidize the solids. The redox catalyst system contains iodine ions, copper at an oxidation state between 1 and 2, a solubilizing agent for cuprous ion which is soluble in water and forms a water-soluble complex with cuprous ion and, at least 20 moles per liter of water the medium havine a pH of less than 2.
