Solubility of ethylene oxide in water
WebAug 29, 2014 · Description. Ethylene oxide is also called oxirane. It is a cyclic ether that is a colorless flammable gas at room temperature, with a faintly sweet odor. It is the simplest epoxide known. Because of its special molecular structure, ethylene oxide easily participates in addition reactions; e.g., opening its ring and thus easily polymerizing. WebWater undergoes molecular exchange between water molecules associated with the polymer and water molecules associated with the solvent, dynamics of major importance for the stabilization of the emulsions. Association of polymeric chains forming reverse aggregates is induced by water over a concentration threshold of 5 wt %.
