在大气压和-9 °C至70°C的温度范围内，乙烯在非极性溶剂（庚烷、十二烷、四氯化碳、二硫化碳和氯苯）到高极性溶剂（异丙醇、丁醇和乙二醇）中的溶解度都有报道。乙烯在非极性溶剂中的溶解度与甲烷、乙烷和丙烷的溶解度之间存在一个有用的关系，这些气体在正常沸点下的蒸发能也与此相关。另一方面，在高极性溶剂中，氢键（H-键合）因子被发现在一个氢键键合溶剂中的溶解度与在其他氢键键合溶剂中的溶解度相关更有用。
Solubilities of ethylene at atmospheric pressure and temperatures ranging from −9°C to 70°C are reported in solvents ranging from the non-polar ones, heptane, dodecane, carbon tetrachloride, carbon disulfide and chlorobenzene to the highly polar ones, isopropanol, butanol and ethylene glycol. A useful relation was observed between ethylene solubilities in non-polar solvents and those of methane, ethane and propane, along with the corresponding energy of vaporization at the normal boiling for those gases. In the highly polar solvents on the other hand, hydrogen bonding (H-bonding) factors were found more useful in relating solubilities in one hydrogen bonding solvent to those in other hydrogen bonding solvents.
