Although a number of methods have been devised for the quantitative estimation of acetone in the urine, at the present time the method of Messinger,2 as modified by Huppert,s is the one most frequently employed, and is usually regarded as the most accurate one at our command.4 A recent paper by Folin5 offers the first satisfactory method for separately determining the acetone and diacetic acid ...

objective: ipomoea mauritiana is used in both ayurveda and folk medicine systems. the tuberous roots are known to be diuretic, depurative, carminative, and anthelmintic. the objective of the current study was to identify phenolic antioxidants from i. mauritiana using spectrophotometric and lc-ms analysis. materials and methods: an activity-guided fractionation and purification process was used t...

A novel acetone-degrading, nitrate-reducing bacterium, strain KN Bun08, was isolated from an enrichment culture with butanone and nitrate as the sole sources of carbon and energy. The cells were motile short rods, 0.5 to 1 by 1 to 2 μm in size, which gave Gram-positive staining results in the exponential growth phase and Gram-negative staining results in the stationary-growth phase. Based on 16...

in this work, hierarchical wo3 core-shell microspheres were synthesized via a facile template-free precipitation method. gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial wo3 nanoparticles. the synthesized and commercial powders were characterized by x-ray diffraction, scanning electron microscop...

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...

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...
