Insight into the reaction mechanism of the conversion of methylbutynol on silica-alumina
The conversion of methylbutynol (MBOH) over commercially available silica-alumina solids was studied. The formation of 3-methyl-3-butene-2-one (MIPK) was explained in terms of the cooperative action of both Bronsted acidic and co-ordinatively unsaturated surface sites. With increasing silica content the number of defect sites decreases and well ordered silica-alumina is formed.
