Thermal behavior and decomposition kinetics of rifampicin polymorphs under isothermal and non-isothermal conditions
(Universidade de São Paulo, Faculdade de Ciências Farmacêuticas, 2010)
The thermal behavior of two polymorphic forms of rifampicin was studied by DSC and TG/DTG. The thermoanalytical results clearly showed the differences between the two crystalline forms. Polymorph I was the most thermally ...
Dehydration and volatilization non isothermic kinetic of the solid state aluminium 8-hydroxyquinolinate
(Editora Unesp, 2001-01-01)
Al(C9H6ON)3.2,5H2O foi precipitado a partir de mistura de solução aquosa do íon alumínio e solução ácida de 8-hidroxiquinolina, e o pH ajustado a 9,5 com solução aquosa de amônia. Curvas TG em atmosfera de nitrogênio ...
