Abstract
The process provided herein is concerned with recovery of hydrocarbons from sulfones using an individual alkali and alkaline-earthy base and a mixture of thereof. As the starting materials are sulfones generated by ODS and commercially inexpensive alkali and alkaline-earth bases, the cost and ecological impact of solid waste disposal is minimized.
