摘要

Nanocompu00d3sitos of hydroxylated fatty acids and nanopartu00cdculas magnu00c9ticas type espinu00c9lio with modified surface, process for obtaining autocatalisado and its applications to this inven ~] refers to a nanocompu00f3sito based on a polymeric matrix comprising nanopartu00edcu These oxides.Where the polymer is preferably derived from hydroxy fatty acids and magnesium oxide manopartu00edculas have organization of the crystalline network of the type spinel. The process of obtaining the poliesterificau00e7u00e3o a hydroxy fatty acid, and preferably the ricinoleic acid is the acid derivative of castor oil.The reaction described occurs when the chains of fatty acids react with each other by means of functional groups present in their structures hidroxilia group and carboxyl group. This reaction occurs in the presence of magnetic nanoparticles of spinel type with the surface modified by hydroxy acid.Such nanopasrtu00edculas modified, in addition to participate in the catalysis of the process are connected by orgu00e3nica with the polymer chain, forming a material with the characteristics of the two materials that form.
