thermoanalytical methods do not yield direct chemical information, Fourier transform infrared spectroscopic (FT-IR) investigations were used in this work.
Aceclofenac (ACE) ([[[2-[(2,6-dichlorophenyl)amino]phenyl]acetyl]oxy]acetic acid) is a non

The current study combines TG and differential scanning calorimetry (DSC) with evolved gas analysis by Fourier transform infrared spectroscopy (FT-IR) to
The rehydration characteristics of a commercially produced hydromagnesite and two basic magnesium carbonates synthetically
produced from Mg(OH)2, are presented. The products were dehydrated and dehydroxylated at 325C before rehydration was attempted. DTA and FT-IR
were used to follow the structural changes that occurred during the rehydration processes. The results obtained for the commercially
and synthetically produced hydromagnesite products indicated that the original symmetry of the groups was reclaimed during
rehydration. This was not observed for the synthetically produced unidentified basic magnesium carbonate product. This investigation
provides insight into the rehydration characteristics of a select group of basic magnesium carbonates.

FT-IR spectroscopy is a useful method for mineralogical analysis of pottery and this method has been used by us for investigation of pottery since 1991 [ 3 – 8 ]. The FT-IR spectroscopy was applied mainly for the identification of crystalline phases
depolymerized CWS fractions, marked as CWS 30 and CWS 60 , were recovered after treatment by freeze–drying. Their molecular sizes, determined by HPLC, were estimated to be ~499,000 (CWS 30 ) and 185,000 (CWS 60 ).
FT-IR spectra of all carboxymethyl
formed during the calcination of sulfur-rich calcareous oil shales from the Negev deposits were analyzed using FT-IR spectroscopy and curve-fitting technique. These techniques allow the identification of individual thermal phases [ 10
