Abstract:
A process for the preparation of alkoxides of the general formula I[M.sup.II (OR).sub.2-y (OR.sup.1).sub.y ].sub.n.multidot.[M.sup.IV (OR.sup.1).sub.4-z (OR).sub.z ] (I)wherein M.sup.II represents magnesium and/or calcium and/or strontium and/or barium, and M.sup.IV represents titanium and/or zirconium and/or hafnium, R is an alkyl residue of from 1 to 18 carbon atoms and R.sup.1 is an alkyl residue of from 1 to 18 carbon atoms, y takes a value of from 0 to 2 and z takes a value of from 0 to 4, and n is a number between 0.001 and 3;by reacting at least one alkoxide of the elements magnesium and/or calcium and/or strontium and/or barium with at least one alkoxide of the elements titanium and/or zirconium and/or hafnium at a temperature which is in the range of the decomposition temperature of at least one of the alkoxides employed.
