Is Thermogravimetry an efficient alternative to gas chromatography in degree of biodiesel conversion?
(2018-05-17)
This work aims to determine if thermogravimetry could be used to determine the degree of conversion of soybean oil to biodiesel without knowing the amount of ester in the sample, comparing the results with the values ...
Ilustration of the influence of the heating rate in thermogravimetry results.
(Soc Brasileira Quimica, 2000-01-01)
The effects of the heating rate on a TG curve of a sample have been widely discussed in the literature. This paper shows the influence of heating rate (beta) in thermogravimetry results when stoichiometry determinations ...
Kinetic evaluation of the dehydration of Yb(III) Lu(III) and Y(III) 4-chlorobenzylidenepyruvate by thermogravimetry (TG)
(2006-01-01)
The dehydration kinetic of Yb, Lu and Y 4-chlorobenzylidenepyruvate was studied by using thermogravimetry and the kinetics parameters obtained by Flynn and Wall method suggest that the dehydration step follows a first order ...

Flame retardant properties of the bark powder of Anadenanthera peregrina var. falcata (Benth.) Altschul (angico) studied by coupled thermogravimetry-Fourier transform infrared spectroscopy
(Elsevier B.V., 2014-03-01)
In this research, the bark powder of Anadenanthera peregrina var. falcata (angico) was characterized by means of simultaneous thermogravimetry-differential scanning calorimetry (TG-DSC) and differential scanning calorimetry ...
Study of the biodegradation of a polymer derived from castor oil by scanning electron microscopy, thermogravimetry and infrared spectroscopy
(Associação Brasileira de Polímeros, 2006-06-01)
The aim of this research is to study the biodegradation of a polyurethane derived from castor oil, which contains polyester segment in its molecular structure, thus becoming susceptible to the microorganisms attack. The ...
Kinetic evaluation of the dehydration of Yb(III) Lu(III) and Y(III) 4-chlorobenzylidenepyruvate by thermogravimetry (TG)
(Editora Unesp, 2006-01-01)
A cinética de desidratação dos 4-clorobenzalpiruvatos de itérbio, lutécio e ítrio foi estudada utilizando a Termogravimetria e os parâmetros cinéticos obtidos pelo método Flynn e Wall sugerem que a etapa de desidratação ...
