propanone การใช้

• I recently dissolved a large quantity of expanded polystyrene in propanone.
• CYP2U1 also metabolizes propanone, acetone, and 2-oxypropane.
• The acronym'APP'signifies the'amino','phenyl'and'propanone'elements of the structure.
• Until the mid-1980s, methamphetamine producers commonly used a liquid chemical called phenyl-2-propanone, or P2P, to make the drug.
• An example is a mixture of trichloromethane ( chloroform ) and 2-propanone ( acetone ), which boils above the boiling point of either pure component.
• From the articles on polystyrene and propanone, I can't work out what this was : phenylethene is a liquid at room temperature and polyphenylethene a brittle solid.
• Acetone ( Propanone ) is the simplest ketone and is separated into three groups in the Joback method : two methyl groups (-CH 3 ) and one ketone group ( C = O ).
• These nonsystematic names are considered retained IUPAC names, although some introductory chemistry textbooks use systematic names such as " 2-propanone " or " propan-2-one " for the simplest ketone ( O " CH 3 ) instead of " acetone ".
• {{ quote | " Any compound ( not being bupropion or a substance for the time being specified in paragraph 2.2 ) structurally derived from 2-amino-1-phenyl-1-propanone by modification in any of the following ways, that is to say,
• The second reaction is the organic reduction of " 1, 2-diphenyl-1-propanone " "'2 "'with lithium aluminium hydride, which results in the same reaction product as above but now with preference for the erythro isomer ( "'2a "').
• And that the name is'original research'is not a reason to delete, when following the IUPAC rules, then you get this name, there may be more correct, then either discuss which one to use, or list more, etc . Note that this is significantly different from IUPAC name ( acetone vs . 2-propanone, etc . ).
• JH I and JH III were tested at nominal concentrations of 5 礛 . Later a trifluoromethyl ketone ( 3-octylthio-1, 1, 1-trifluoro-2-propanone ) was shown to be a highly potent, high affinity slow, tight binding inhibitor of the JH esterase of Trichoplusia ni, the same Lepidopteran which was used in the other study in this section.
• In late 1969, Joe Shapiro, an agent for the federal Bureau of Narcotics and Dangerous Drugs ( later to become part of the Drug Enforcement Administration ), was assigned to locate an illegal methamphetamine ( " meth " ) production lab believed to be on Whidbey Island in phenyl-2-propanone ( P2P ), a necessary ingredient in meth manufacture which had become difficult to obtain, in return for half of the resulting output.
• Scientific Instrument Services, Volatile Organic Emissions from Automobile Tires, 1999, Santford V . Overton & John J . Manura : Tire " Brand A were found to contain numerous straight and branched chain hydrocarbons, aldehydes, alcohols, ketones, furans and benzene derivatives . " Tire brand B was . . . " found to contain high concentrations of the compounds sulfur dioxide ( DOT ), 2-methyl-1-propene, 2-propanone, 2-methyl-2-pentene, 2, 4-pentanedione, acetic acid and 2, 4-( 1H, 3H ) pyrimidinedione . " Chemicals extracted from raw tires in this study would be found in crumb rubber, which is made by grinding feedstock tires.
