Synthesis of 2,5-dihydrofuran |
| 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 DEG -120 DEG C. in the presence of solid mercuric oxide. |
