3,3-dimethyl-2-butanone (NMR Spectrum) This page requires the MDL Chemscape Chime Plugin. If released to air, a vapor pressure of 31.5 mm Hg at 25 °C indicates 3,3-dimethyl-2-butanone will exist solely as a vapor in the atmosphere. Propanone. Molecular Weight 100.16 . Key absorptions are marked on the spectra.
Key absorptions are marked on the spectra. It is used as a solvent and can be converted to butanone which is an industrial solvent. This is a saturated ketone, and the C=O band appears at 1715.
You will find that this is very similar to the infra-red spectrum for ethyl ethanoate, an ester. It is also used in the synthesis of rubber auxiliaries and for the selective extraction of rare earth elements. Figure 8.
It also dissol This page requires the MDL Chemscape Chime Plugin. Again, there is no trough due to the O-H bond, and again there is a marked absorption at about 1700 cm-1 due to the C=O. Select the IR spectrum that corresponds best to 3-hydroxy-2-butanone. Select the IR spectrum that corresponds best to 3-hydroxy-2-butanone. EC Number 200-920-4. (See the Hint for the structure. ) This is a saturated ketone, and the C=O band appears at 1715. IR Spectra. Key absorptions are marked on the spectra. Figure 7. The carbonyl stretching vibration band C=O of saturated aliphatic ketones appears: C=O stretch. Beilstein/REAXYS Number 1209331 . Molecular Weight 100.16 .
IR Spectroscopy Tutorial: Ketones The carbonyl stretching vibration band C=O of saturated aliphatic ketones appears at 1715 cm -1 . (See the Hint for the structure. ) Attenuated Total Reflectance Infrared (ATR-IR) Spectrum of 3-Methyl-2-butanone with properties. (See the Hint for the structure. ) Horizontal axis in wavenumber (cm-1) for most IR Absorptions are observed as sharp or broad reductions in the % of light transmitted through the sample.

Note the C–H stretches (around 2991) of alkyl groups. IR spectra of solids and liquids are usually obtained by dissolving the sample in a relatively IR transparent solvent such as CCl 4 and using simple liquid cells. 3,3-Dimethyl-2-butanone is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). aliphatic ketones 1715 cm-1; alpha, beta-unsaturated ketones 1685-1666 cm-1; Figure 8. shows the spectrum of 2-butanone.

PubChem Substance ID … 3,3-Dimethyl-2-butanone's production and use as a fungicide and herbicide intermediate may result in its release to the environment through various waste streams.
M1265 | 78-93-3. sec-Butyl Alcohol is also known as 2-Butyl alcohol and sec-Butanol. 3-Methyl-2-butanone is employed predominantly as an intermediate for the production of pharmaceuticals, herbicides, and dye precursors. MDL number MFCD00008846. Ungraded products supplied by Spectrum are indicative of a grade suitable for ge Soluble in water, it has a range of uses including as an industrial solvent. MDL number MFCD00008846. IR Spectrum of Butanone 4 Vertical axis in %Transmittance (most often) for liquid phase IR. Infrared Spectrum of Ethanol. Linear Formula CH 3 COC(CH 3) 3. Synonym: 2-Butanone peroxide solution, Methyl ethyl ketone peroxide solution Linear Formula: C 2 H 5 C(OOH)(CH 3 )OOC(OOH)(CH 3 )C 2 H 5 Molecular Weight: 210.22
A solid could also be ground to a fine paste with NUJOL TM (a mixture of highly purified hydrocarbons) and the resulting 'mull' studied directly. Conjugation of the carbonyl group with carbon-carbon double bonds or phenyl groups, as in alpha, beta-unsaturated aldehydes and benzaldehyde, shifts this band to lower wavenumbers, 1685-1666 cm -1 . EC Number 200-920-4. 2-butanone found in: 2-Butanone, Reagent, ACS, Methyl Ethyl Ketone, Exceeds A.C.S. The infra-red spectrum for a ketone. Beilstein/REAXYS Number 1209331 .
absorptions No significant absorption 12.4 No … It's usually not necessary to mark any of the bands in the fingerprint region (less than 1500 cm-1).
