Abstract
SINCE the crystal structure of hexamethyl benzene at room temperatures has been accurately determined by Robertson and Brockway1, it seemed of interest to investigate the intra- and inter-molecular interactions of the methyl groups. Pauling2 has suggested that a lower transition point at — 165° C. marks the beginning of rotation of methyl groups. It is then desirable to elucidate the mechanism of an upper transition found at 110° C. The thermal data of these transitions as well as those of the melting point have been reported by Parks and his co-workers3. We have made a preliminary dilatometric investigation of this substance from room temperature to the liquid temperature. The results are shown in the accompanying graph.
