Process for preparing propene |
摘要 |
A multistage process for preparing propene, in which the first stage is the reaction of 1-butene, 2-butene and isobutene to give propene, 2-pentene and 2-methyl-2-butene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the second stage is separation of the propene and 2-pentene/2-methyl-2-butene formed; the third stage is reaction of the 2-pentene and 2-methyl-2-butene with ethehe to give propene, 1-butene and isobutene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the fourth stage is separation of the propene and 1-butene/isobutene formed and returning the 1-butene and isobutene formed to the first stage. |
