Descripción : In the present work, an X-ray diffraction (XRD) and thermal study of calcium undecanoate is presented. The measured highresolution XRD powder pattern of the synthesized salt at room temperature, using synchrotron radiation, showed that the salt is a mixture of monohydrated and anhydrous calcium undecanoate. Calcium undecanoate monohydrate proved to have a monoclinic cell with a symmetry described by the P21=a space group. The structure dehydrates at about 1001C. After dehydration, the salt undergoes a phase transformation which results in a thermotropic mesophase. Further heating of the salt leads to decomposition and melting. Ketones are the probable products of decomposition at 4001C. r 2003 Elsevier Science (USA). All rights reserved.
