Taking into account the importance of thermal stability in the liquid crystals field, the study presents the thermal behavior
of some ferrocene containing Schiff bases. Some other kinetic characteristics, such as reaction order (n), activation energy (Ea) and pre-exponential factor (lnA) have been also evaluated. The thermal stability series of Schiff bases was established analysis associated with three parameters
(Td, Tmax, Ea) is: S6<S4<S3<S5<S1<S2.
