All soaps can be prepared by heating soap-forming fatty acids with the Al salts of lower fatty acids such as Al formite or acetate at temperatures > the boiling points of the corresponding acids such as formic or acetic acids. Temperatures of about 140º-250º are suitable. It is advantageous to work under vacuum especially toward the end of the reaction, as the soap forming fatty acids paraffin oxidation products are suitable.
