ABSTRACT
The soaps of alkaline earth's and transition elements and closed ‘d’ orbitals were prepared by the double decomposition method by the reaction between metallic salts and sodium palmitate. The thermal stability of these soaps was studied in order to throw the light on their suitability for using as catalysts or lubricants. The soaps of alkaline earth's were found to be more stable than transition and ‘d’ closed shell soaps.Se han preparado jabones de tierras alcalinas y elementos de transición y orbitales “d” completos por el método de la descomposición doble mediante la reacción entre sales metálicas y palmitato sódico. La estabilidad térmica de estos jabones se estudio con el fin de arrojar luz sobre su idoneidad para su uso como catalizadores o lubricantes. Se encontró que los jabones de las tierras alcalinas son más estables que los de transición y que los jabones con la capa “d” completa.
