Реферат: Fluorination of lanthanum oxide with ammonium fluoride is studied. Among all the known rare earth elements, lanthanum oxide is most commonly used as a stabilizing catalyst component, in particular in the hydrogenation of heteroatomic compounds of biofuel. Previous thermodynamic and thermogravimetric studies point to the multistage fluorination of La2O3 with ammonium fluoride. The reaction kinetics is correctly described by the kinetic equation of a contracting sphere with the activation energy equal to 33.65 kJ/mol. The X-ray phase analysis of the formed crystal phase showed that complex fluorides like (NH4)3La2F9 ⋅ H2O and (NH4)3LaF6 ⋅ 0.5H2Oare formed as impurities during the interaction of La2O3 with NH4F in addition to the major product (LaF3).
