Preliminary Results

The infrared spectra of rare earth acetates have been studied to examine the metal-acetate bonding. The thermal decomposition of rare earth acetates as well as lead and copper acetates have been investigated in detail by employing thermogravimetric analysis and differential thermal analysis. Thermal decomposition of calcium dicarboxylates (malonate to sebacate) have been studied employing t.g.a. and d.t.a. Infrared spectra of the dicarboxylates have also been studied. Preliminary results on the products of decomposition of dicarboxylates have been reported.

Optimization Parameters

Magnesium salt flame retardant is a new filler flame retardant agent, and can release the water and absorb the latent heat during the thermal decomposition, which can effectively inhibit the polymers decomposition and cool the combustible gas generated in the case of fire. In this paper, the magnesium salt flame retardant is synthesized in different conditions. Then the thermal decomposition features of the magnesium salt flame retardants with the smallest particle diameters are characterized by using thermogravimetric analysis and differential thermal analysis. Finally, on the basis of this analysis, optimization parameters for preparing the magnesium salt flame retardant with good thermal decomposition performance are obtained, which may be helpful for guiding the preparation of high-performance magnesium salt flame retardants and providing a beneficial reference.

Several papers have been described on the thermal stability of the sweetener, C12H19Cl3O8 (Sucralose). Nevertheless no study using thermoanalytical techniques was found in the literature. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC) and infrared spectroscopy, have been used to study the thermal stability and thermal decomposition of sweetener.

The 2-carboxybenzaldehyde-1H-benzotriazol-1-aceylhydrazone (C16H13N5O3) has been synthesized and used in preparing thirteen novel rare earth complexes. The complexes were characterized by elemental analysis, FT-IR, and UV-Vis, and the formula is RE (C16H11N5O3)·NO3·xH2O·yC2H5OH (RE=La, Ce, Pr, Nd, Sm, Eu, Tb, Ho, Er, Yb) and RE(C16H12N5O3)2·NO3·5H2O (RE=Gd, Dy, Y) .The thermal decomposition processes of the thirteen complexes were studied by thermal gravimetric technology and their apparent activation energy values were calculated by Kissingers and Ozawass method.
