Title: Mesophase from anthracene oil-based pitches

Abstract

This work deals with the preparation of the mesophase from two pitch-like materials obtained from anthracene oil by oxidative thermal condensation (AOP-1) and the subsequent thermal treatment and distillation of AOP-1 (AOP-2). The mesophase was obtained by the controlled pyrolysis (440-470{degree}C and different periods of residence times) and subsequent sedimentation of the samples. In the case of the pitch prepared by oxidative thermal condensation, a dynamic pressure of 5 bar was applied during the pyrolysis. The pressure was a critical parameter, and its influence was also investigated. The results show that AOP-1 requires higher temperatures and/or residence times to develop mesophase than AOP-2. After sedimentation, a sample consisting of mainly mesophase was produced in all of the cases. The characterization of the mesophases by means of techniques, such as elemental and thermogravimetric analysis and optical microscopy, showed that anthracene oil-based derivatives are appropriate precursors for producing QI-free mesophase with suitable properties for the fabrication of a wide range of carbon materials. 26 refs., 5 figs., 3 tabs.
