Process for the extraction of butadiene by solvent from a mixture of compound of C4 that boil next to the butadiene and for the recovery of butadiene as a product of the process.

摘要

The present invention relates to a method for the extraction of butadiene by solvent from a mixture of hydrocarbon having four carbon atoms per molecule, whose method inherently produces tar compounds, the extraction process is operated with a level of loading. Tar, with the solvent used, no more than about 1.6% by weight.
