Abstract
Disclosed is a process for removing acid soluble oils, produced as an undesirable by-product of an HF catalyzed alkylation reaction, from a liquid containing a sulfone compound. The process includes the use of a solvent to extract the acid soluble oils from a sulfone-containing fluid that has previously been neutralized by a treating step.
