USE OF DIETHYLENETRIAMINE 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. |

1. A method of scavenging carbon disulfide (“CS2”) in a hydrocarbon stream comprising:
(a) contacting said hydrocarbon stream with a treatment composition to form a reaction product of said CS2 and said treatment composition, wherein said treatment composition comprises at least one CS2 scavenger and at least one phase transfer catalyst therein and wherein said CS2 scavenger comprises 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 are integers from 0 to 10; and
(b) separating the reaction product from said hydrocarbon stream. |
