Recent studies have confirmed
that model 
has a stable
liquid phase confined to a rather narrow temperature range;
in this letter we
determine the phase diagram of model 
and show that also this fullerene possesses a liquid phase
whose existence range is wider than that of .
A "corresponding state"behaviour
of and ,
emerging from a description
in terms of reduced quantities of
both the interaction potential and the phase diagrams' parameters,
is then extended to higher-order
fullerenes. Critical- and triple-point densities and temperatures of
, 
and 
are thereby predicted.
The decreasing accuracy of such a representation
of 
phase behaviour
with increasing n is discussed
in relation to the model potential features.
