|Title:||Kinetic Study Of Chelates Of 2,2,6,6-tetramethyl-3,5-heptanedione With Some Lanthanide Elements|
|Abstract:||The thermal decomposition reactions of crystalline chelates of general formula Ln(thd)3 (Ln=La, Pr, Nd, Sm and Gd; thd=2,2,6,6-tetramethyl-3,5-heptanedione) have been studied by isothermal thermogravimetry. Several models were proposed initially to calculate the kinetic parameters by iso-thermal method, thus the time reduced method was used to define the best kinetic models. The Avrami-Erofeev (Am=2, 3 and 4) and R1 and R2 models presented good agreement with experimental data, as well as, linear correlation coefficient (r) and standard deviation (s).|
