USE OF POLYAMINES AS A CS2 SCAVENGER IN ISOPRENE PRODUCTION

摘要

Methods for scavenging carbon disulfide ("CS₂") from hydrocarbon streams using treatment compositions comprising at least one CS₂ scavenger and at least one phase transfer catalyst therein. The CS₂ scavenger may comprise at least one polyamine with the general formula: H₂N-(R₁-NH)_x-R₂-(NH-R₃)_y-NH₂ wherein R₁, R₂, R₃ may be the same or different H, aryl or C₁-C₄ alkyl; and x and y may be integers from 0 to 10. A hydrocarbon product with a reduced concentration of CS₂ therein.
