Additional information
The water solubility has been investigated taking into account the available data from literature sources and performing an internal assay.
The experiment performed by registrant, following internal method and procedures, indicated the substance as water soluble: 1200 mg/l, at room temperature.
Some literature data indicate the substance as water soluble, up to 2000 mg/l. No details about the tested substance and conditions are available and this could explain why there are two publications that indicate the substance as non water soluble (Sethi, 2003 and AAVV, 2014).
In order to investigate deeper this property, data on the analogues acetophenone and butyrophenone have been considered; their stuctures present a methyl group less and more, respectively, than propiophenone. The impact of the structural differences is expected to determine a greater/lower solubility of acetophenone and butyrophenone, respectively, respect to the water solubility of propiophenone. However, all the three substances are expected to be soluble in water, i.e. more than 100 mg/l and the available information seem to confirm this expectation.
Acetophenone is described as water soluble from literature sources. The aqueous water solubility of acetophenone has been determined using HPLC and the solubility was found to be 6.13 g/l (0.051 mol/l) at 25 °C (Southworth and Keller, 1986). A further publication reports the experimental water solubility of the substance at approximately 3234 mg/l at 25 °C (Kühne et al, 1995).
The water solubility of acetophenone, propiophenone and butyrophenone has been estimated to be 4484, 1193 and 332.9 mg/l, respectively, using WSKOW v.1.42.
The substance is concluded to be soluble in water.
