Abstract

Tetrahydrofuran is produced from furan obtained by the catalytic decarbonylation of furfural by treatment of said furan with a caustic alkali followed by hydrogenation in the presence of a metal hydrogenation catalyst, such as finely divided nickel, platinum or palladium in the pure state or on an inert support. The preferred starting material is distilled furan obtained from furfural by vapour phase decarbonylation in the presence of steam over mixed chromites as described in Specification 575,362, [Group IV]. The furan is extracted with a dilute aqueous solution of caustic alkali such as sodium or potassium hydroxides, preferably containing 1 to 15% by weight of caustic alkali. The extraction may be carried out in a continuous liquid-liquid extractor. The hydrogenation may be effected at ordinary or elevated temperature, liquid phase continuous hydrogenation using tetrahydrofuran as a reaction medium being preferred.
