✦ Synopsis

The products obtained by heating sucrose at 6.9 MPa hydrogen, with and without hydriodic acid, at temperatures between 200 and 400°C have been examined by solid-state and solution '"C NMR and FTIR spectroscopy. In the absence of hydriodic acid, pyrolysis of sucrose produced an aromatic char, even at low temperatures, and no chloroform-soluble material. In the presence of hydriodic acid, almost all the sucrose was converted to chloroform-soluble material (tar) at 400°C. Heat treatment of this tar yielded mesophase similar in appearance to that obtained from coal tar.
