PURIFICATION OF HYDROCARBONS BY USING AMINE ADDITIVE TO REMOVE C52 |
摘要 |
Isoprene and butadiene are purified by treating a petroleum refinery C4 stream or petroleum refinery C5 stream which contain butadiene or isoprene or relatively pure butadiene or isoprene and carbon disulfide by treatment of these streams with from about 1 to about 7 equivalents of a polyamine. The polyamine reacts with the CS2 impurity to form the dithiocarbamate salt. The hydrocarbon is then separated from the dithiocarbamate salt and any excess unreacted polyamine by water washing this stream or by flash distilling of the hydrocarbon. |
