“…9 Because 2-butene can be transformed to isobutene, light elements (such as propene), and heavy oligomers over acid catalysts at a higher temperature, it is necessary to investigate a selective reaction for the production of 1-butene. [10][11][12] The results presented so far with respect to positional isomerization mainly used catalysts that were modified based on Al 2 O 3 . [13][14][15][16] To generalize the research results on the positional isomerisation of 2-butene, catalysts with fewer Brönsted acid sites and many Lewis acid and H-bond acid sites became useful for the synthesis of 1-butene.…”

The objective of the present study is to investigate the catalytic performance of mesoporous alumina that were prepared via spray pyrolysis for double bond migration from 2-butene to 1-butene. The mesoporous alumina particles were prepared via spray pyrolysis by changing the types of organic surfactants and Al precursors. The texture and acidic properties of mesoporous alumina were analyzed through N2 adsorption, SEM, ammonia-temperature programmed desorption, and FT-IR of adsorbed pyridine. The morphologies and texture properties of the mesoporous alumina were found to have been strongly influenced by the combination of the Al precursor and the structure-directing agents. The mesoporous alumina samples had two kinds of acidic sites: a Lewis acid site and a H-bonded weak acid site. 1-Butene was produced selectively through double bond migration of 2-butene over all of the mesoporous alumina catalysts. The catalyst prepared by using a chloride compound as an aluminium precursor and CTAC as a structure-directing agent showed the highest activity in the double bond migration of 2-butene, which was attributed to its large surface area and an overall high amount of acid sites.
