Critical Evaluation:
A survey of reported compositions along the saturation curve (sat), and compositions of coexisting phases in equilibrium (eq.) for the system 2-methyl-2-propanol-benzene-water is given in Table 69.
Saturation curve
The ternary system 2-methyl-2-propanol-benzene-water forms a miscibility gap of type 1. Only one binary system benzene-water forms a miscibility gap. These binary data were compiled and critically evaluated in a previously published SDS volume, Ref. 3. The recommended values of mutual solubility at 298 K are
x
'

=0.9970,

=0.000 409. The mutual solubility of benzene and water was also reported by Simonsen and Washburn,

(

=0.0003); these are consistent with the recommended values. Letcher

reported data only in graphical form. Therefore these data are not compiled. The plait point estimated by Letcher and Siswana

was
x
1
=0.16 and
x
2
=0.02, while the maximum alcohol concentration on the binodal curve is
x
1
=0.41. This point is consistent with the results of Simonsen and Washburn measurements,
x

=0.38.
