Abstract
Some new pyrimidine derivatives have been synthesized and their decomposition characteristics have been studied by thermogravimetric and differential scanning calorimetric analysis. The thermal stability and some kinetics parameters of decomposition were evaluated from thermograms. It is observed that depending upon the structure, substitutions, thermal stability and decomposition kinetics varies in different compounds.

Se sintetizaron algunos nuevos derivados de pirimidina y se estudiaron sus características de descomposición mediante análisis termogravimétrico y calorimétrico diferencial de barrido. La estabilidad térmica y algunos parámetros cinéticos de descomposición se evaluaron a partir de los respectivos termogramas. Dependiendo de la estructura y las sustituciones, la estabilidad térmica y la cinética de descomposición varían entre los diferentes compuestos. Palabras clave: análisis termogravimétrico, calorimetría diferencial de barrido, estabilidad térmica, parámetros cinéticos
