Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The solubilities of potassium carbonate in organic solvents are determined by flame photometry. Solubilities of 7.5 g/L (DMF), 47 g/L (DMSO), 4.6 g/L (N,N-dimethylacetamide), 16 g/L (sulfolane), and 23.7 g/L (N-methyl-2 -pyrrolidone) were found at ambient temperature.

Conclusions:
The solubilities of potassium carbonate in organic solvents are determined to be 7.5 (DMF), 47 (DMSO), 4.6 (N,N-dimethylacetamide), 16 (sulfolane), and 23.7 g/L (N-methyl-2 -pyrrolidone) at ambient temperature.
Executive summary:

The solubilities of potassium carbonate in organic solvents are determined by flame photometry. Solubilities of 7.5 (DMF), 47 (DMSO), 4.6 (N,N-dimethylacetamide), 16 (sulfolane), and 23.7 g/L (N-methyl-2 -pyrrolidone) were found at ambient temperature.

Key value for chemical safety assessment

Additional information

Reliable data from peer-reviewed handbooks and a publication are available. Potassium carbonate is insoluble in ethanol. The solubilities of potassium carbonate in other organic solvents at ambient temperature are 7.5 g/L in DMF, 47 g/L in DMSO, 4.6 g/L in N,N-dimethylacetamide, 16 g/L in sulfolane, and 23.7 g/L in N-methyl-2 -pyrrolidone.
