Nonisothermal Kinetics of Dehydration Process of [Sm (m-ClBA)3phen]2·2H2O and [Sm(p-ClBA)3phen]2·2H2O
چکیده انگلیسی
Compounds [Sm(m-ClBA)3phen]2·2H2O and [Sm(p-ClBA)3phen]2·2H2O(m-ClBA=m-chlorobenzoate, p-ClBA=p-chlorobenzoate, phen=1,10-phenanthroline) were prepared. The dehydration processes and kinetics of these compounds were studied from the analysis of the DSC curves using a method of processing the data of thermal analysis kinetics. The Arrhenius equation for the dehydration process can be expressed as lnk=38.65-243.90x103/RT for [Sm(m-ClBA)3phen]2·2H2O, and lnk=38.70-172.22x103/RT for [Sm(p-ClBA)3phen]2·2H2O. The values of ΔH#, ΔG#, and ΔS# of dehydration reaction for the title compounds are determined, respectively.
