Abstract: A process for the purification of a crude liquid feed stream comprising 1,4-butanediol and a minor amount of 2-(4->hydroxybutoxy)-tetrahydrofuran and/or precursors thereof wherein the process comprises passing the crude feed in the presence of hydrogen in a reaction zone over a heterogeneous liquid tolerant copper catalyst in the liquid phase at hydrogenation conditions and recovering a purified stream of 1,4-butanediol having a lower amount of 2-(4-hydroxybutoxy)-tetrahydrofuran than the crude liquid feed stream.
