Changes in Texture and Catalytic Activity of Nanocrystalline MgO during Its Transformation to MgCl2 in the Reaction with 1-Chlorobutane

The interaction of 1-chlorobutane with nanocrystalline MgO at 200−350 °C has been found to result in both stoichiometric and catalytic dehydrochlorination of 1-chlorobutane to isomers of butene and simultaneous topochemical conversion of MgO to MgCl2. The obtained magnesium chloride appeared to be an active catalyst for the dehydrochlorination reaction, so the rate of 1-chlorobutane conversion grows significantly with time. Changes in the MgO texture during the topochemical reaction are discussed and their effect on the catalytic activity is estimated.
