Study on the KOH + K2CrO4 + K2CO3 + H2O System

The phase equilibrium data for the quaternary system KOH + K2CrO4 + K2CO3 + H2O between 20 °C and 80 °C were measured, and the phase diagram was constructed. Simultaneously, concentration of K2CrO4 in aqueous solution of KOH was compared with that in aqueous solution of KOH saturated with K2CO3. Fur...

Zusammenfassung:	The phase equilibrium data for the quaternary system KOH + K2CrO4 + K2CO3 + H2O between 20 °C and 80 °C were measured, and the phase diagram was constructed. Simultaneously, concentration of K2CrO4 in aqueous solution of KOH was compared with that in aqueous solution of KOH saturated with K2CO3. Furthermore, analyses and discussions are made on the crystalline areas in the phase diagram.
