Abstract: A stream containing styrene and mixed xylenes, such as may be recovered from pyrolysis gasoline, is fractionated to obtain a stream containing ortho-xylene and styrene. Styrene is separated from the latter stream by an extraction process which employs succinonitrile as the solvent. Styrene is selectively absorbed by the succinonitrile, and is subsequently recovered from the resulting extract phase.

Abstract: In a process for dehydrocyclization of C.sub.6 -C.sub.12 alkanes in the presence of steam and a bed of a catalyst containing a Group IIA or IIB metal aluminate and a Group VIII metal, an oxygen containing gas is injected into the catalyst bed. The results of the oxygen injection are the internal generation of heat, a lower required steam to hydrocarbon ratio, and increased yield of aromatics.

Abstract: Butadiene is produced in relatively pure form by an oxidative dehydrogenation process in which a crude butadiene stream comprising butadiene, butylenes, vinyl acetylene and propylene is first extractively distilled with an extractant consisting of a sulfolane/acetone mixture. From a purified stream consisting essentially of butadiene and vinyl acetylene, the vinyl acetylene in a second extractive distillation step is removed using a sulfolane/acetone mixture as the extractant to produce a pure butadiene stream.
