Abstract
A process for preparation of mesophase-mesogenic high temperature pitch from anthracene fraction by thermal treatment of raw material under pressure of inherent vapor or inert gas with subsequent isolation of desired product. Before thermal treatment components boiled away to the temperature of 320 °C are steamed, and isolation of desired product is performed by vacuum thermal treatment during between 5 and min. and pressure between 2.5 10-6 and 5 • 10-2 MPa.
