Ternary Solution Equilibria Case of Enantiomers

What is not considered here is partial miscibility in solid state also occurring in chiral systems. How this is represented in a ternary solubility phase diagram is shown in Section 7.2. 

Quaternary Systems Case oTRedprocal Salt Pairs 

As already introduced in Section 3.1.4, the reciprocal salt pairs represent industrially relevant examples of quaternary systems. They play an important role in the production of inorganic salts via the so-called redprocal conversion in water. Industrial apphcations are the manufacture of K2SO4 and Na2C03 on the basis of mined potash ores according to the following readions  

In principle, what is done in reciprocal conversion is an exchange of anions and cations between the salt pairs. The underlying heterogeneous equilibria at a certain temperature can be represented in a square phase diagram as derived in Sedion 3.1.4. 

For application purposes, the reciprocal conversion according to Equation 3.12 shall be discussed in more detail. The conversion of sodium chloride with
