TL;DR: In this paper, the adsorption of acetone on the Ge(100)-2 × 1 surface has been investigated using multiple internal reflection infrared spectroscopy and density functional theory quantum chemistry calculations and was found to be under thermodynamic control at room temperature.
Abstract: The adsorption of acetone on the Ge(100)-2 × 1 surface has been investigated using multiple internal reflection infrared spectroscopy and density functional theory quantum chemistry calculations and was found to be under thermodynamic control at room temperature. Acetone undergoes attachment at the carbonyl oxygen with loss of an α hydrogen at room temperature on the Ge(100)-2 × 1 surface to form an enol-like adduct. This so-called ene reaction has not been seen on the Si(100) surface, on which the reaction of acetone is under kinetic control and instead a less thermodynamically favored [2 + 2] addition across the carbonyl bond is observed. At low temperature, acetone adsorbs via dative-bond formation with the surface, which we find to be too weak to remain at room temperature in contrast to the stronger dative bonds formed by amines on the Si(100) and Ge(100) surfaces. There is evidence that the acetone ene product may undergo oxygen migration and insertion into Ge−Ge bonds, especially at elevated surfac...

TL;DR: In this article, the photodegradation of dyeing wastewater in the presence of acetone, which performs as a solvent and/or a photo-sensitizer, was investigated.

TL;DR: In this paper, a novel upgrading method of bio-oil produced from fast pyrolysis of biomass was reported, where Methanol, as hydrogenation liquid donor, was used in the hydrogenation process instead of hydrogen gas.

TL;DR: In this article, activated carbons prepared from agricultural waste were modified to introduce surface acid sites by treatment with HNO3 or H2SO4, and they were studied as heterogeneous catalysts for the solvent-free acetalisation of acetone with glycerol to produce 2,2-dimethyl-1,3-dioxolane-4methanol (solketal).
