BORDIER, María C; DE MORAN, Juana A; NAVARRO, Ercilia A y GOMEZ, María Inés. Preparation and Physicochemical Properties of Iron (III) Salt of the N1-Acetyl Sulfanilamide. Inf. tecnol. [online]. 2007, vol.18, n.2, pp.77-82. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642007000200012.
In the present work the iron (III) salt of the N1-acetyl sulfanilamide, know as iron (III) sulfacetamide, was prepared by using a conventional precipitation technique. This was done with the purpose of studying their physicochemical properties and to propose eventual applications of the same one. The composition, density, superficial area, solubility, constant of the solubility product, and aging parameters of the compound were determined. The thermal decomposition process was studied using thermo gravimetric (TGA) and differential thermo gravimetric (DTA) analysis in oxygen atmosphere. Infrared spectroscopy and chemical analysis were used to identify intermediate products. The process occurs at various stages, and the final product is iron(III) oxide that is formed at relatively low temperatures. This suggests the application of metallic derivates of sulfacetamide to obtain oxides.
