Abstract
A process for preparing a furan compound by contacting a diolefin such as butadiene with a catalyst at a low pressure and a low temperature is provided. In this process, a diolefin, an oxygen-containing gas and water containing HCl are contacted with a catalyst which is a support having deposited thereon copper chloride, and alkali metal chloride and at least one of palladium chloride and iodide, usually cuprous iodide. Temperature of the reaction is usually in the range of about 80.degree.-125.degree. C. and the pressure is usually in the range of about 1-5 atmospheres. Cyclic operation between furan production and catalyst oxidation is also provided.
