Abstract
Improved process for preparing 2,5-dihydrofuran by the dehydration of 1-butene-3,4-diol in the presence of a soluble mercury salt as catalyst in a dissociating solvent at a neutral or acidic pH at an elevated temperature, the improvement characterized in that the dehydration is carried out at a pH of 4 to 7 at 80.degree.-120.degree. C. in the presence of solid mercuric oxide.
