Definitions
- pitch hydrogenation Another way to produce spinnable mesophase pitch involves pitch hydrogenation.
- pitch is treated with a hydrogenating agent, e.g. Tetrahydroquinoline, hydrogenated and, after filtration and separation of the solvent by distillation, thermally treated under vacuum to produce the mesophase.
- a hydrogenating agent e.g. Tetrahydroquinoline
