OSTI ID:6504760
This patent describes an improvement in a process for separating at least one cycloalkane containing 5-10 carbon atoms per molecule from a least one close-boiling alkane by extractive distillation of a feed consisting essentially of the at least one cycloalkane and the at least one alkane. The improvement comprises employing a solvent.
