Headspace analysis in GC–MS in different temperatures previously identified by TG and DSC was also performed and provided information about thermal behavior of quinones and their degradation products. Results showed that 1,4-benzoquinone, 1,4-naphthoquinone and 9,10-anthraquinone are thermally stable over the range of the temperature evaluated, while 1,2-naphtoquinone and 9,10-phenanthraquinone decompose above 100 °C and 215 °C, respectively. Overall, results indicate that the molecular structure influences strongly the course of the thermal decomposition of these quinones and it is a determining factor for its thermal stability.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-08-25T13:24:45Z No. of bitstreams: 1 Eliane Teixeira Sousa.pdf: 602149 bytes, checksum: 23f704d28e932d82171b53feb2a5d6ff (MD5)Made available in DSpace on 2014-08-25T13:24:45Z (GMT).
