Abstract
The process entails adding salt in an amount of 1% to 5% by weight slurry to an aqueous slurry of cyclodextrin-guest complex at a temperature of 100.degree. C. to 150.degree. C. for a period of 5 minutes to 2 hours and a pressure of 15 psia to 70 psia to prevent the slurry from boiling and to cause the complex to break apart. The individual cyclodextrin and guest are then recovered.
