Absolute rate coefficients for the title reaction, HO + HOCH(2)C(O)CH(3)--> products (R1) were measured over the temperature range 233-363 K using the technique of pulsed laser photolytic generation of the HO radical coupled to detection by pulsed laser induced fluorescence. The rate coefficient displays a slight negative temperature dependence, which is described by: k(1)(233-363 K) = (2.15 +/...

This work describes a molecular system where it is possible to effectively control the interconversion between two different stable conformational states, using selective narrow-band near-infrared irradiation. Monomers of hydroxyacetone (HA) isolated in low temperature argon matrices at 15 K exist exclusively in the conformational ground state Cc. Narrow-band near-infrared vibrational excitatio...

The structure of hydroxyacetone (HA) isolated in an argon matrix (at 12 K) and in a neat solid phase (at 12-175 K) was characterized by using infrared (IR) spectroscopy. The interpretation of the experimental results was supported by high-level quantum chemical calculations, undertaken by using both ab initio (MP2) and density functional theory methods. A potential-energy surface scan, carried ...

Acetol – a dehydration product of glycerol can be selectively reduced to 1,2-propanediol and acetone through hydrogenation dehydroxylation reactions, thereby providing platform toward an efficient upgrading biomolecules. To shed light on the relationship between reactivity electrode structure, we report electrochemical reduction acetol low-index platinum single crystals their corresponding epit...
