The phase diagram is as for type I but with the addition of a three phase (liquid-liquid-gas)line ending at an upper critical end point UCEP and a (liquid-liquid) critical line starting from the UCEP and rapidly approaching high pressures This type can occur with or without azeotropy Type III This phase diagram has two distinct critical

a line of discontinuous transitions terminates at a critical point and the isotherms ex-hibit singular behaviour in the vicinity of this point The phase diagram is simpler in appearance because the symmetry H ??H ensures that the critical point occurs at H c = M c = 0
