Abstract
The invention relates to a process for preparing 1-octene by reacting 1,3-butadiene with a telogen of the formula H—X—Y—H, where X is O, N, S or P and Y is C, N or Si and X and Y bear, depending on their valence, further substituents, in the presence of a telomerization catalyst to form a telomer of the formula H2C═CH—CH2—CH2—CH2—CH═CH—CH2—X—Y—H, partially hydrogenating the telomer to form a 1-substituted 2-octene of the formula H3C—CH2—CH2—CH2—CH2—CH═CH—CH2—X—Y—H and dissociating the 1-substituted 2-octene to give 1-octene.
Claims31
A process for preparing 1-octene, which comprises:
- (I) reacting 1,3-butadiene with a telogen of the formula H—X—Y—H, where X is O, N, S or P and Y is C, N, or Si and X and Y bear, depending on their valence, further substituents, in the presence of a telomerization catalyst to form a telomer of the formula:
- H2C═CH—CH2—CH2—CH2—CH═CH—CH2—X—Y—H (II),
- (II) hydrogenating the telomere to form a 1-substituted 2-octene of the formula:
- H3C—CH2—CH2—CH2—CH2—CH═CH—CH2—X—Y—H (III);
- and
- (III) dissociating the 1-substituted 2-octene to give 1-octene and other dissociation products (IV).
