Franciscus Antonius Hubertus Schreinemakers
Schreinemakers, Franciscus Antonius Hubertus
Born Sept. 1, 1864, in Roermond; died 1945. Dutch physical chemist.
Schreinemakers became a professor at the University of Leiden in 1901. His research dealt mainly with heterogeneous equilibriums in ternary and multicomponent systems. It was Schreinemakers who proposed the residue method (1893), which made possible a determination of the chemical composition of solid phases crystallizing in ternary systems without separating these phases from the mother liquor. He also developed methods for depicting the equilibriums in ternary (1892) and quaternary (1907-J09) systems, investigated equilibriums in ternary systems having regions of separation (1913), and established phase diagrams for many ternary and quaternary aqueous salt systems. Schreinemakers’ contributions are widely used in physicochemical analyses, petrography, metallurgy, and halurgy.
