2073a.     LECKY, J. A., HALL, W. K., AND ANDERSON, R. B.  Adsorption of Water and Methanol on Coal.  Nature, vol. 168, 1951, pp. 124-125; Chem. Abs., vol. 46, 1952, p. 11,630.

          Results do not agree with a feature of the Ellis’s theory of the structure of coal.  The true surface area of coal is probably not measured by adsorption of MeOH and H₂O, since these polar compounds are not physically adsorbed in the usual sense, and hence are not amenable to the Brunauer-Emmett-Teller treatment for derivation of surface area.
