Production of cyclic ethers |
| abstract |
A process for the preparation of cyclic ethers which comprises reacting an alkanediol in which the hydroxyl groups are separated by a chain of at least four carbon atoms in the liquid phase of a catalyst comprising a palladium salt and a copper salt, and recovering the cyclic ether thus formed by a separation step such as distillation. The reaction is carried out in a molecular oxygen gaseous atmosphere. A preferred catalyst is palladium chloride in combination with a copper salt such as cupric chloride or cupric nitrate. |
