This method of preparation is described in detail in UK. Patent specification 825,878 and in published Australian patent application 29673/57. Alternatively, they may be prepared by heating aluminium alcoholates with car boxylic acids so. as to liberate alcohol and form acyloxy aluminium alcoholate compounds, and further heating the latter compounds.
