The thermal decomposition of lanthanum(III) and cerium(IV) chelates of
dibenzoylmethane anthranilic acid was studied by TG. The mechanism of
the decomposition reactions were found to be random nucleation as est
ablished from TG data. Activation energies, E, pre-exponential factors
, A, entropy of activation, DELTAS, orders of reaction, n, were calcul
ated from the TG curves using mechanistic and non-mechanistic integral
equations.
