Exempel på hur man kan använda ACETONE i en mening

• Typically, the position of the carbonyl group is denoted by a number, but traditional nonsystematic names are still generally used for the most important ketones, for example acetone and benzophenone.
• Tetryl is a yellow crystalline solid powder material, practically insoluble in water but soluble in acetone, benzene and other solvents.
• Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.
• Other syntheses that have been examined but not implemented include Wacker oxidation of 2-butene and oxidation of isobutylbenzene, which is analogous to the industrial production of acetone.
• His acetone production method was of great importance in the manufacture of cordite explosive propellants for the British war industry during World War I.
• The first step is the ionization of alkyl halide in the presence of aqueous acetone or ethyl alcohol.
• It typically produces deep red varietal wines with smoky, bramble and earthy flavours, sometimes with notes of bananas and tropical fruit, but has been criticised for sometimes smelling of acetone.
• The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.
• Sixteen organic compounds were detected, four of which were seen for the first time on a comet, including acetamide, acetone, methyl isocyanate and propionaldehyde.
• Lecithin can easily be extracted chemically using solvents such as hexane, ethanol, acetone, petroleum ether or benzene; or extraction can be done mechanically.
• The compound crystallizes from a heated solution of mercuric iodide, potassium iodide, and precisely 2% water in acetone.
• He accomplished this by mixing purified urease with acetone and then chilling it; the chilled solution produced crystallized urease.
• It is produced by the reaction of acetone and hydrogen peroxide to yield a mixture of linear monomer and cyclic dimer, trimer, and tetramer forms.
• They consist of an aluminum disc with a coating of nitrocellulose lacquer with acetone added to make a varnish.
• Note: Acetylene cylinders contain an inert packing material, which may be agamassan, and are filled with a solvent such as acetone or dimethylformamide.
• The condensation of acetone (hence the suffix 'A' in the name) with two equivalents of phenol is catalyzed by a strong acid, such as concentrated hydrochloric acid, sulfuric acid, or a solid acid resin such as the sulfonic acid form of polystyrene sulfonate.
• Several entrainers can be used for this specific process: benzene, pentane, cyclohexane, hexane, heptane, isooctane, acetone, and diethyl ether are all options as the mixture.
• The enzyme metabolizes both endogenous substrates, such as ethanol, acetone, and acetal, as well as exogenous substrates including benzene, carbon tetrachloride, ethylene glycol, and nitrosamines which are premutagens found in cigarette smoke.
• On the other hand, dipolar aprotic solvents such as dimethyl sulfoxide and acetone are soft solvents with a preference for solvating large anions and soft bases.
• Secoisolariciresinol diglucoside can be isolated from de-fatted (hexane extraction) flaxseed by extraction of the lignan polymer precursor with a water/acetone mixture, followed by acetone removal and alkaline hydrolysis.
