Title: Research priorities in chemistry

Abstract

The methods of chemical thermodynamics embodied in MULTEQ provide a valuable tool in the investigation of corrosion in steam boilers. Consequently, it is important to support research activities that contribute the most to the well being of MULTEQ. Such research may be divided into modeling needs and data needs. The most important modeling needs of MULTEQ include: (1) an improved treatment of the thermodynamics of electrolyte solutions that changes in a continuous fashion from the present treatment of dilute solutions to one for concentrated solutions more suited to wet molten salts; (2) improved correlations of the entropy change for reactions that, along with the use of the isocoulombic rule, will enable us to establish more reliably the species formed by the association of ions in aqueous solutions at high temperatures. The most important data needs of MULTEQ include: (1) solubility measurements, especially of new substances found in corrosion environments; (2) pH measurements with the hydrogen electrode, especially in conjunction with solubility measurements of oxides and hydroxides, to establish the species formed by metal ions in high temperature aqueous solutions; and (3) continued support of existing programs of isopiestic, calorimetric, conductivity, density, and volatility measurements in high temperature aqueous systems.
