Abstract
A C4-olefin mixture having a 1,3-butadiene content of from 100 to 500 ppm and a content of 1,2-dienes of less than 10 ppm is described. The present invention further provides a process for preparing this C4-olefin mixture and provides for its use in a metathesis reaction for preparing 2-pentene and/or 3-hexene.
Claims4
A C4-olefin mixture comprising a 1,3-butadiene content of from 100 to 500 ppm and a content in cumulated dienes of 1 to 10 ppm, wherein the 1-butene content in the mixture is at least 30% by weight, based on the mixture.
