  • Use of diethylenetriamine as a CS2 scavenger in isoprene production
    Patent number: 9981889
    Abstract: 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.
