| Zusammenfassung: | Provided is a method for producing a propylene oligomer with which a low-branched propylene oligomer can be obtained with a high selectivity. This method for producing a propylene oligomer comprises: an oligomerization step for oligomerizing propylene at a temperature lower than 160 DEG C in the presence of at least one selected from the group consisting of a catalyst containing a crystalline molecular sieve and a catalyst containing phosphoric acid; a fractional step for obtaining a fraction containing a propylene trimer, a propylene tetramer, or a mixture thereof; and an isomerization step for isomerizing the propylene trimer, the propylene tetramer, or the mixture thereof contained in the fraction in the presence of a catalyst containing phosphoric acid. |
