An endothermic peak appeared around 258°C, associated with a slight weight loss in GDTA curve which might have been mainly associated with the dehydroxylation of NaOH Arai, 1996.
Alrededor de los 258 °C se presenta un pico endotérmico, relacionado con una leve pérdida de peso en la curva TG, que se puede asociar, principalmente, a la deshidroxilación del NaOH Arai, 1996.
