ABSTRACT:
Alkoxy ethoxides, for example 2-methoxy ethoxide, of aluminum and magnesium or aluminum and calcium, are provided. These compounds are of the formula MAl.sub.2 (O--CH.sub.2 --CH.sub.2 --O--R).sub.8 wherein M is calcium or magnesium and wherein R is an alkyl of 1 to 4 carbon atoms; they are liquids at about 25.degree. C. and about 1 atmosphere of pressure and are produced by reacting aluminum and magnesium or calcium with mono-alkyl ethers of ethylene glycol. Methods for hydrolyzing the compounds to obtain oxides of the formula MgAl.sub.2 O.sub.4 and CaAl.sub.2 O.sub.4 are disclosed. For example, magnesium aluminum octa-(2 methoxy ethoxide) is produced, using ethylene glycol monomethyl ether (methyl "Cellosolve") as a reagent; the material is hydrolyzed and heated to form MgAl.sub.2 O.sub.4.
