Recently, the influence of the preparation method of various MgO samples on their catalytic activity in the MPV reaction of cyclohexanone with 2-propanol has been reported 202). The oxides were prepared by various synthetic procedures including calcination of commercially available magnesium hydroxide and magnesium carbonate calcination of magnesium hydroxides obtained from magnesium nitrate and magnesium sulfate sol-gel synthesis and precipitation by decomposition of urea. It was concluded that the efficiency of the catalytic hydrogen transfer process was directly related to the number of basic sites in the solid. Thus, the MgO (MgO-2 sample in Table IV) prepared by hydration and subsequent calcination of a MgO sample that had been obtained from commercially available Mg(OH)2 was the most basic and the most active for the MPV process, and the MgO samples with similar populations of basic sites exhibited similar activities (Table IV). 

A classic example of a solid—fluid ceramic powder synthesis reaction is that of calcination and dehydration of natural or synthetic raw materials. Calcination reactions are common for the production of many oxides from carbonates, hydrates, sulfates, nitrates, acetates, oxalates, citrates, and so forth. In general, the reactions produce an oxide and a volatile gaseous reaction product, such as CO2, SOg, or HgO. The most extensively studied reactions of this type are the decompositions of magnesium hydroxide, magnesium carbonate, and calcium carbonate. Depending on the particular conditions of time, temperature, ambient pressure of CO2, relative humidity, particle size, and so on, the process may be controlled by a surface reaction, gas diffusion to the reacting...

Hydrated magnesium sulfate occurs in nature as the minerals kieserite and epsomite. The salt is mined in large scale from these and other naturally occurring minerals. The salt also is prepared in the laboratory by the action of sulfuric acid on magnesium oxide, hydroxide, or carbonate followed by evaporation and crystallization ... 

By heating methane with excess oxygen, air, or ozonized air at red heat (600° to 1000° C.) under pressure in the presence of porous non-metallic surfaces as pumice, brick, slag, asbestos, etc., it has been claimed that methanol and formaldehyde may be produced. The products are condensed at atmospheric pressure by a counter current of cold air or gas. The catalyst might also contain substances such as oxides and hydroxides of alkalies or alkaline earths, magnesium or calcium chlorides or copper sulfate which are hydrated at ordinary temperatures but lose water at high temperatures. 

The suspension is then treated in an external reactor with fresh milk of lime containing further magnesium oxide. The magnesium hydrogen sulfite and sulfate react with calcium hydroxide, forming magnesium sulfite and sulfate, which are recycled, and precipitate calcium sulfite hemi-hydrate and gypsum (29.12,29.13).
