Sulpholane is prepared by hydrogenating sulpholene at a temperature of from 10 to 40 C. in the presence of supported palladium oxide as catalyst. The hydrogenation is suitably effected in isopropanol or an isopropanol-sulpholane mixture at elevated pressure. The catalyst may be reactivated by oxidation at a temperature of up to 300 C.
