Motivated by the recent discovery of gas-phase interstellar vinyl alcohol, CH₂CH(OH), we present laboratory experiments on this molecule's solid-phase formation. Through a combination of reaction chemistry, infrared spectroscopy, isotopic substitution, thermal annealings, and independent syntheses, we have identified vinyl alcohol in proton-irradiated H₂O+C₂H₂ices and have measured its column density at ∼15 K. UV photolysis of H₂O+C₂H₂ ices at ∼15 K also produces vinyl alcohol. It is suggested that vinyl alcohol is formed in interstellar ices and then ejected into the gas phase, where it might undergo additional reactions.
