Implementations described herein generally relate to methods for purifying alpha-olefins. The alpha-olefins may be used to form drag reducing agents for improving flow of hydrocarbons through conduits, particularly pipelines. In one implementation, a method of increasing alpha-olefin content is provided. The method includes providing an olefin feedstock composition having an alpha-mono-olefin and at least one of a diolefin having an equal number of carbon atoms to the alpha-mono-olefin and/or a triolefin having an equal number of carbon atoms to the alpha-mono-olefin. The method further includes contacting the olefin feedstock composition with ethylene in the presence of a catalyst composition including an olefin metathesis catalyst. The method further includes reacting the olefin feedstock composition and ethylene at metathesis reaction conditions to produce an alpha-olefin product comprising the alpha-mono-olefin and alpha-olefins having fewer carbon atoms than the alpha-mono-olefin.

Methods of producing a 2,4-dienal acetal compound and a 2,4-dienal compound useful as synthesis intermediates of a sex pheromone compound having a conjugated diene structure or a conjugated triene structure. More specifically, a method produces a 2,4-dienal acetal compound of Formula (2): R.sup.1CHCHCHCHCH(OR.sup.2)(OR.sup.3), including a step of subjecting a 2-enal acetal compound having a leaving group X at position C5 and being expressed by Formula (1): R.sup.1CHXCH.sub.2CHCHCH(OR.sup.2)(OR.sup.3) to an elimination reaction in the presence of a base to obtain the 2,4-dienal acetal compound (2); and a method for producing a 2,4-dienal compound of Formula (3): R.sup.1CHCHCHCHCHO, further including a step of deprotecting the 2,4-dienal acetal compound (2) to obtain the 2,4-dienal compound (3).
