Phenylacetone, also known as phenyl-2-propanone, is an organic compound with the chemical formula C 6 H 5 CH 2 COCH 3. It is a colorless oil that is soluble in organic solvents. It is a mono-substituted benzene derivative, consisting of an acetone attached to a phenyl group. As such, its systematic IUPAC name is 1-phenyl-2-propanone.
This is followed by a step in which the phenyl group migrates from the benzyl carbon to the adjacent oxygen and a water molecule is lost, producing a resonance stabilized tertiary carbocation. The concerted mechanism of this step is similar to the mechanisms of the Baeyer–Villiger oxidation [ 6 ] and Criegee rearrangement reactions, and also ...
Propiophenone can be prepared by Friedel–Crafts reaction of propanoyl chloride and benzene.It is also prepared commercially by ketonization of benzoic acid and propionic acid over calcium acetate and alumina at 450–550 °C: [1]
Synthesis is relatively simple but entails risk with flammable and corrosive chemicals, particularly the solvents used in extraction and purification. The six major routes of production begin with either phenyl-2-propanone (P2P) or with one of the isomeric compounds pseudoephedrine and ephedrine. [95]
How to make non-Newtonian liquid: 2.5 cups of corn starch. 1 cup of water. 1 tablespoons of paint. After all ingredients are in a medium-sized mixing bowl, mix until well incorporated.
According to Primus Green Energy, the STG+ process converts natural gas into 90+-octane gasoline at approximately 5 US gallons per million British thermal units (65 litres per megawatt-hour). [4] The energy content of gasoline is 120,000 to 125,000 British thermal units per US gallon (9.3 to 9.7 kilowatt-hours per litre), making this process ...
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
Comprehensive two-dimensional gas chromatography, or GC×GC, is a multidimensional gas chromatography technique that was originally described in 1984 by J. Calvin Giddings [1] and first successfully implemented in 1991 by John Phillips and his student Zaiyou Liu. [2] GC×GC utilizes two different columns with two different stationary phases. In ...
