derivatograph type Q-1500, samples of 100 mg, α-Al 2 O 3 served as reference material in air static atmosphere. From TG, DTA and DTG curves the solid intermediate products decomposition were determined and were confirmed by the IR spectra of sinters. In sinters
thermogravimetry and differential thermal analysis (TG-DTA, Setaram TGDTA 92) in the temperature range 30–800 °C at a heating rate of 10 °C min −1 , under an ambient atmosphere. The intermediate and final compounds of thermal decomposition of the
compounds and the solid intermediates of thermal decomposition were recorded on an AVATAR 330 FT-IR Thermo Nicolet spectrometer using KBr pellets (2 mg/200 mg KBr), in the range 4000–400 cm −1 . Thermal decomposition was studied in nitrogen

non-isothermal stages (heating and cooling) did not exceed 3 min. Both annealing methods were realized in air, without intermediate grinding and mixing. The phase composition of the examined samples was measured using an ARL X'TRA X
the turnover frequencies (TOF), which correspond to the number of molecules transformed per acidic site (in fact the number of olefinic intermediates formed on the metallic sites which react on the protonic sites) follow a decreasing order: PtHZSM-5
of more than one intermediate prior to the formation of the final reaction product. The rapid scan of the orange solution showed the λ max of the intermediate, C 4 , to be 473 nm ( Fig. 1 ). The UV–VIS spectra of IO 4 − , TOL and Mn II indicated
Introduction Intermediate-temperature solid oxide fuel cells (IT-SOFCs) have attracted considerable attention worldwide for their high efficiency and low environmental impact and played an important role in the hydrogen fuel
obtained from the molar heat capacity [ 15 , 16 ]. In this paper, the phase change properties and the thermal stability of an N - tert -butyloxycarbonylated organic synthesis intermediate, ( S )- tert -butyl 1-phenylethylcarbamate (Scheme 1 , C 13 H 19
