Propene gas solubilities at 101.3 kPa pressure are reported in n ‐octane, chlorobenzene, acetone, acetic acid, ethyl acetate, n ‐butanol, N‐N ‐dimethyl formamide ( DMF ) and ethylene glycol for a range of temperatures. These data, along with data from the literature, were used to show the qualitative effects of unsaturation of the gas component on the solubility in various solvents ranging from non‐polar to highly polar and associated solvents. This involved a comparison, when data were available, of the solubilities of ethane, ethylene and acetylene, then of butane, isobutane, isobutylene, trans‐2‐butene and 1,3‐butadiene as well as of propane and propene (propylene). The differences in solubilities could be explained using solubilities expressed as a molecular interaction parameter ( mip ) and by identifying several different types of molecular interactions. For associating solvents these effects can be summarized as follows: mip of acetylene > mip of ethylene > mip of ethane, also mip of propylene > mip of propane and mip of butadiene > mip of isobutylene≥ mip of trans‐2‐butylene > mip of butane > mip of isobutane.
