Nanocyrstals of MgO having 4 nm average crystallite sizes with 450-550 m(2)
/g surface area were prepared by the Aero-gel preparation method (AP-MgO).
Dehydrohalogenation of 1-chlorobutane was performed using AP-MgO as a catal
yst: And l-butene is the selective product formed even after several cycles
of 1-chlorobutane injections. AP-MgO was allowed to react with Cl-2, which
resulted in the formation of a highly reactive adduct which has a capabili
ty to selectively chlorinate propane. (C) 2001 Acta Materialia Inc. Publish
