Tóm tắt

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