Nanocyrstals of MgO having 4 nm average crystallite sizes with 450–550 m²/g surface area were prepared by the Aero-gel preparation method (AP-MgO). Dehydrohalogenation of 1-chlorobutane was performed using AP-MgO as a catalyst; And 1-butene is the selective product formed even after several cycles of 1-chlorobutane injections. AP-MgO was allowed to react with Cl₂, which resulted in the formation of a highly reactive adduct which has a capability to selectively chlorinate propane.
