Early evidence for the metabolic activity of acetone was derived from studies showing a partial disappearance of administered doses of the compound (1, 2). It is clear from these investigations, and from subsequent work (3,4), that most of the acetone excreted as volatile iodoform-forming substance appears in the exhaled air; a smaller fraction is excreted in the urine. Schwarz (1) demonstrated...

[1] Acetone is one of the most abundant carbonyl compounds in the atmosphere and it plays an important role in atmospheric chemistry. The role of the ocean in the global atmospheric acetone budget is highly uncertain, with past studies reaching opposite conclusions as to whether the ocean is a source or sink. Here we use a global 3-D chemical transport model (GEOS-Chem) simulation of atmospheri...

in iranian traditional medicine, there are some report regarding the anticonvulsant effect of ferula gummosa boiss. in this study, anticonvulsant activity, neurological deficits and lethality of the root acetone extract of this plant were evaluated in mice. the extract exhibited dose-dependent prevention of tonic seizures induced by pentylenetetrazole (ed50 = 154.4 mg/kg). however, the extract ...

Comparatively few methods are available for the determination of the acetone bodies in blood. Marriott (1913-14, b) has described a method by which the nephelometric technique described by him (1913-14, a) could be applied to the determination of these substances in blood. Scott-Wilson’s reagent was used in this determination (Scott-Wilson, 1911). Marriott used this method in studying the relat...

A crucial chain-branching step in autoignition is the decomposition of ketohydroperoxides (KHP) to form an oxy radical and OH. Other pathways compete with chain-branching, such as “Korcek” dissociation γ-KHP a carbonyl acid. Here we characterize formation its formic acid+acetone products from observations n-butane oxidation two complementary experiments. In jet-stirred reactor measurements, KHP...

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...

background: woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. stem and flower extracts are previously flourished for their antibacterial activity. leaves are also equally important, which are preliminary screened for their bioactive components in present study. objective: evaluation of antibacterial activity of leaves of w. fruticosa and detection of thei...

In this work, molecular dynamics (MD) was performed to simulate the dynamic processes of 1:4 acetone/nitrogen permeating through different Al2O3 membranes by Materials Studio 2.2 software package. Three modeling systems were constructed applying different modeling box lengths as well as different hollow size and texture of Al2O3 membranes to compare different permeation behaviors. In each syste...
