ABSTRACT:
The invention relates to a process for preparing cyclic polyethers from cyclic alkylene carbonates in the presence of a solvent, wherein the process is carried out in the presence of a solvent selected from the group containing a carbonyl moiety, nitrile moiety or mixture thereof. In addition, ionic catalysts may be employed to increase the selectivity to cyclic polyether.
