用红外光谱研究了1-丁烯在H-ZSM-5分子筛上的吸附和反应。吸附的1-丁烯在低于250 K的真空下转化为顺式和反式-2-丁烯，并在室温下观察到吸附的2-丁烯的二聚反应。所产生的二聚体被暂时指定为3，4-二甲基-3-己烯，其通过其烷基链与酸性OH基团氢键合。因此，由于没有发生质子从H-ZSM-5向二聚体的转移，反应在二聚化时终止。
Adsorption and reaction of l-butene on H-ZSM-5 were studied by FT-IR spectroscopy. The adsorbed l-butenes were converted to cis-and trans-2-butenes below 250 K under evacuation, and dimerization of the adsorbed 2-butenes was observed at room temperature. The produced dimer was tentatively assigned to 3,4-dimethyl-3-hexene which hydrogen-bonded to the acidic OH groups with its alkyl chains. Therefore, the reaction terminated at the dimerization since proton transfer from H-ZSM-5 to the dimer did not occur.
