Acetone, butanol and ethanol (ABE) mixture separation from dilute aqueous fermentation products is an important process for the biofuel industry. Here, we present a novel approach for ABE recovery using microwave induced membrane distillation (MD). Carbon nanotubes (CNTs) and …

Synthetic methods on the site are updated continuously by chemists working in academic and industrial research laboratories. From Wikipedia. Acetone (systematically named 2-propanone) is the organic compound with the formula (CH 3) 2 CO. It is a colorless, volatile, flammable liquid, and is the simplest ketone.. Acetone is miscible with water and serves as an important solvent in its own right, typically for cleaning purposes in the laboratory. About 6.7 million tonnes were produced worldwide in 2010, mainly for use ChemSpider; Content; Description: A chemical structure database providing fast access to over 100 million structures, properties and associated information. ChemSpider is a database of chemicals.ChemSpider is owned by the Royal Society of Chemistry. A V 4 C 3 T x based acetone sensor delivers good performance, as demonstrated by its low working temperature of 25 °C, low detection limit of 1 ppm (lower than the 1.8 ppm diabetes diagnosis threshold), and high selectivity towards acetone in a mixed gas of acetone and water vapor, hopefully showing promise for application in the much faster and earlier diagnosis of diabetes.

University Avenue, Little Se hela listan på de.wikipedia.org The first example of visible light promoted fluoroalkylation reactions initiated via noncovalent interactions between acetone and fluoroalkyl iodides is presented. The reaction system features synthetic simplicity, mild reaction conditions without any photoredox catalyst, and high functional group tolerance. The as-formed hierarchical SnO 2 /α-Fe 2 O 3 composites exhibit remarkable selective acetone-sensing properties, in which the optimum composition of SnO 2 /α-Fe 2 O 3 with Sn : Fe = 1.5 exhibits the best response towards 200 ppm acetone gas under the operating temperature of 270 °C (with gas response R a /R g = 9.3), with a fast response/recovery speed (6 s/7 s), as well as excellent We report enhanced amperometric sensing response of electrospun tungsten oxide (WO3−x) nanofibers towards acetone with low concentrations (1.2–12.5 ppm) at 350 °C. Scanning and transmission electron microscopy (SEM and TEM) revealed the nanocrystalline nature of tungsten oxide nanofibers with a diameter in t Dimethyldioxirane (DMDO), also referred to as Murray's reagent in reference to Robert W. Murray, is a dioxirane derived from acetone and can be considered as a monomer of acetone peroxide. It is a powerful yet selective oxidizing agent which finds use in organic synthesis. The lower critical solution temperature (LCST) of poly-N-isopropylacrylamide (p-NIPAM) diminishes when a small volume of acetone is added to the aqueous polymer solution, and then increases for further additions, producing a minimum at a certain acetone concentration.

Acetone, organic solvent of industrial and chemical significance, the simplest and most important of the aliphatic (fat-derived) ketones. Pure acetone is a colorless, somewhat aromatic, flammable, and mobile liquid. Learn more about the structure and uses of acetone in this article.

The alpha,beta-unsaturated carbonyl compound, E,E-dibenzylidene acetone (dba or 1,5-bis-penta-1E,4E-dien-3-one), is readily synthesised by simple base-mediated aldol condensation of two equivalents of benzaldehyde with acetone in the presence of sodium hydroxide in a water/ ethanol solvent medium at room temperature (ref. 1).

Above −20 °C, thioacetone readily converts to a polymer and a trimer, trithioacetone. It has an extremely potent, unpleasant odour, hence thioacetone has been considered as the worst-smelling chemical. Thioacetone was first obtained in 1889 by Baumann and Fromm, as a minor impurity in their synthesis of A V 4 C 3 T x based acetone sensor delivers good performance, as demonstrated by its low working temperature of 25 °C, low detection limit of 1 ppm (lower than the 1.8 ppm diabetes diagnosis threshold), and high selectivity towards acetone in a mixed gas of acetone and water vapor, hopefully showing promise for application in the much faster and earlier diagnosis of diabetes.

C 3 H 6 O. acetone Hexafluoroacetone (HFA) is a chemical compound with the formula (CF 3) 2 CO. It is structurally similar to acetone; however, its reactivity is markedly different.It a colourless, hygroscopic, nonflammable, highly reactive gas characterized by a musty odour. Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It liberates hydrogen cyanide easily, so it is used as a source of such.
