Resumo: 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 are studied. For this purpose the compound Sm(CH3SO3)(3). 2(3-picNO) was considered beta of 2,5; 5; 10; 20 and 40 degrees C min(-1) in dynamic air atmosphere were obtained. The results are in agreement with proposed stoichiometry for beta equal to 2,5 and 5 degrees C min(-1). However, using a higher beta the same results were not obtained resulting in false stoichiometry determinations.
