Abstract
The phase equilibrium data for the quaternary system KOH + K2CrO4 + K2CO3 H2O between 20 degreesC and 80 degreesC were measured, and the phase diagr am was constructed. Simultaneously, concentration of K2CrO4 in aqueous solu tion of KOH was compared with that in aqueous solution of KOH saturated wit h K2CO3. Furthermore, analyses and discussions are made on the crystalline areas in the phase diagram.
