Bakhuis Roozeboom

There is a vast literature on ternary systems in particular, mention should be made of the work of H. W. Bakhuis Roozeboom, Die Heterogenen Gleichgewichte (Amsterdam, 1901-1911), work continued by F. A. H. Schreinemakers and R. Vogel [50]. See also the work of Findlay and of Bancroft Cf. esp. G. Masing, Terndre Systeme (Leipzig, 1933). Eng. Trans, by B. A. Rogers (London, 1944).

Nor was Ostwald the only one in the 1890s to recognize the worth of Gibbs. The Dutch physical chemist, Hendrik Willem Bakhuis Roozeboom (1854-1907), publicized Gibbs s phase rule throughout Europe and did so most effectively.

Roozeboom s maxim would often be quoted, e.g., as late as 1941, in H.R. Kruyt, De Wegder Wetenschap (Amsterdam H.J. Paris, 1941). 

Again, it should be pointed out that it was not only charity that moved the professors to undertake this move for their students. As Bakhuis Roozeboom added to the proposal, another main reason was fear for depopulation of the university and the subsequent superfluity of its chemistry departments. But whatever the motives, the proposal was accepted, and in the same year Andreas Smits, chief chemist of the municipal gasworks, was appointed the new Lecturer in Technical Chemistry.

Principles of phase equilibria after Gibbs (5) and Van der Waals (6) supply the ordering procedure for these phenomena. The application of these principles has been greatly stimulated by the work of Bakhuis Roozeboom (7).

The question of how the solvent water would behave around and above its critical point was first addressed by the Dutch chemist Bakhuis Roozeboom and his school, who were experts at measuring and classifying the phase separation of binary and ternary mixtures, including sohd phases. By 1904, Bakhuis Roozeboom had explored the case of the liquid-vapor-solid curve intersecting the critical line of a binary mixture in two critical endpoints and predicted that this would also happen in aqueous solutions of poorly soluble salts, as his successors indeed confirmed in 1910. His experiments and classification scheme pertain to a multitude of both non-aqueous and aqueous binary and ternary systems.
