TL;DR: In this article, the photolysis of deuterated acetone has been investigated, and it was found that E3 −½E2=9.7 kcal, where E2 and E3 are the activation energies of the above reactions.
Abstract: The photolysis of acetone has been investigated between 100°C and 300°C. The rates of production of carbon monoxide, methane and ethane have been measured over a range of acetone pressures from 3.9 to 100 mm and with a thirty‐fold variation of light intensity. The methane and ethane formed can be quantitatively accounted for by the equations CH3+CH3=C2H6, CH3+CH3COCH3=CH4+CH2COCH3. It is found that E3—½E2=9.7 kcal., where E2 and E3 are the activation energies of the above reactions. The photolysis of deuterated acetone has also been investigated, here E3′—½E2′=10.3 kcal. The collision theory ``steric'' or ``P'' factor for the second reaction is less than 10−3 in each case.

TL;DR: In this article, the amount of acidic sites of a series of SnO 2 MoO 3 binary oxides was determined by n -butylamine titration and correlated to the catalytic activity to form acetone in the oxidation of propylene.

TL;DR: The performance of a new NADP-regeneration system, based on the use of alcohol dehydrogenase (ADH)-acetone, has been investigated for the regioselective oxidation of cholic acid to 12-ketochenodeoxycholic acid.
Abstract: The performance of a new NADP-regeneration system, based on the use of alcohol dehydrogenase (ADH)-acetone, has been investigated for the regioselective oxidation of cholic acid (1) to 12-ketochenodeoxycholic acid (2). Enzymes stabilities and substrate and/or product inhibitory effects under defined synthetic reaction conditions have been evaluated. The optimized system, based on a 4% w/v solution of 1 in a reaction mixture containing 25% v/v acetone, allowed the preparative scale transformation of 1 into 2 with a 92% conversion.

TL;DR: In this article, mesoporous hollow nanospherical (MHS) MnxCo3−xO4 solid solutions with tunable Mn/Co molar ratios in the spinel-type cubic crystal phase, fabricated by a facile solvothermal alcoholysis approach, have been developed to catalyze acetone oxidation.
