Description

Description générale

Potassium citrate tribasic monohydrate is the tripotassium salt of citric acid. It has been proposed as a promising organic salt for the formation of aqueous two-phase system (ATPS). UCON (temperature-responsive polymer) + potassium citrate ATPS has been studied.

Application

Potassium citrate tribasic monohydrate (tribasic potassium citrate) may be added as a promoter during the preparation of activated carbon-supported CuCl₂ + PdCl₂ + NaOH catalyst. This catalyst was employed for the conversion of ethanol to diethyl carbonate (DEC).1 It may be used to compose the fermentation medium for Aspergillus niger 72-4. It may be used as a standard to investigate the influence of Bergenia ligulata rhizome (BLR) on CaC₂O₄ crystallization.
