Mechanical Interatomic Bond Formation in Ethanol and Methanol–Ethanol Mixture by Laser‐Driven Shock Waves

Abstract

AbstractMolecules, which were predicted to be produced by C−C or C−O bond formation between ethanol molecules induced by a laser‐driven shock wave, were identified by gas chromatography–mass spectrometry. Moreover, the laser irradiation of a methanol–ethanol mixture revealed the formation of C−C and C−O bonds between both components. Particularly, four hemiacetals (methoxymethanol, 1‐methoxyethanol, ethoxymethanol, and 1‐ethoxyethanol) were identified in the Ar‐saturated alcohol samples, whereas acetalization dominated sufficiently in the CO2‐saturated samples, significantly reducing the hemiacetals. It was verified that some molecules were produced by the dropout of an ethanol part during the C−C or C−O bond formation, supporting the contribution of laser‐driven shock waves.
