Acetone is considered moderately hygroscopic compared to ethanol. For information on the rate of water absorption by acetone versus ethanol and other commonly used laboratory solvents, a publication in the Journal of Chromatographic Science, Volume 20, Issue 5, May 1982, Pages 213-217 may serve as a valuable reference.
To dry acetone, salts can be used. Additionally, there are drying reagents and acetone products available with low water content, such as 179124 ACS reagent (≥99.5%), 650501 HPLC Plus (≥99.9%), and AX0116 OmniSolv®.
