Abstract
The phase behaviour of cyclo-octanol has been studied at temperatures between 100 and 370 K and pressures up to 300 MPa with the aid of differential thermal analysis. Two new high pressure modifications (solid Iii and IV) have been found and accordingly two sets of triple point values: (a) the (solid I + solid II + solid III) triple point at 105 MPa and 277 K; (b) the (solid II + solid Iii + solid IV) triple point at 130 MPa and 278 K. Both phases solid III and IV are supposed to be orientationally disordered (“plastic”) phases.Keywords
