The Thermodynamic Method of Vitrification of Copaíba Oil-Resin (Copaifera Langsdorffii)

The development of the method of vitrification of copaiba oil resin (COR) consisted of three protocols named by Hp-1, Hp-2
and Hp-3. The vitrified heteropolymers were analyzed using photographs, optical microscopy, scanning electron microscopy,
thermogravimetric analysis and differential thermal analysis. The results showed that there was the formation of vitrification and,
therefore, the vitrification of the COR. The image results showed that the surfaces have rough and orderly microregions. Thermal
analyzes showed that among the heteropolymers made with the Hp-1 and Hp-2 protocols are similar by TGA and DTA. Suggesting
greater thermal stability than Hp-3.
