Acetone (CH3COCH3)

Dissociation of acetone radical cation (CH3COCH3(+*) --> CH3CO(+) + CH3(*)): an ab initio direct classical trajectory study of the energy dependence of the branching ratio.

The nonstatistical dissociation of acetone radical cation has been studied by ab initio direct classical trajectory calculations at the MP2/6-31G(d) level of theory. A bond additivity correction has been used to improve the MP2 potential energy surface (BAC-MP2). The energy dependence of the branching ratio, dissociation kinetics, and translational energy distribution for the two types of methy...

Toxicological Profile for Acetone

Rubrene endoperoxide acetone monosolvate

The title acetone solvate, C(42)H(28)O(2)·C(3)H(6)O [systematic name: 1,3,10,12-tetra-phenyl-19,20-dioxapenta-cyclo-[10.6.2.0(2,11).0(4,9).0(13,18)]icosa-2(11),3,5,7,9,13,15,17-octa-ene acetone monosolvate], is a photooxygenation product of rubrene (systematic name: 5,6,11,12-tetra-phenyl-tetra-cene). The mol-ecule bends at the bridgehead atoms, which are linked by the O-O transannular bond, wi...

The Determination of Acetone

In the determination of P-oxybutyric acid through oxidation to acetone by the Shaffer bichromate method’ with subsequent estimation of the acetone by Messinger’s iodimetric titration,” difficulty was experienced in obtaining the t,heoretical amount of acetone from known amounts of pure P-oxybutyric acid. It was suspected that either the Messinger titration was inaccurate or that the acetone was...
