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.
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 ...
Methyl isobutyl ketone (MIBK, 4-methylpentan-2-one) is an organic compound with the condensed chemical formula (CH 3) 2 CHCH 2 C(O)CH 3. This ketone is a colourless liquid that is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.
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]
3,4-Methylenedioxypropiophenone, also known as 3,4-(Methylenedioxy)phenyl-1-propanone (MDP1P), is a phenylpropanoid found in some plants of the genus Piper and is an isomer of 3,4-methylenedioxyphenyl-2-propanone (MDP2P).
The six major routes of production begin with either phenyl-2-propanone (P2P) or with one of the isomeric compounds pseudoephedrine and ephedrine. [ 95 ] One procedure uses the reductive amination of phenylacetone with methylamine , [ 96 ] P2P was usually obtained from phenylacetic acid and acetic anhydride , [ 97 ] and phenylacetic acid might ...
In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
The cumene process can be modified to produce phenol and a mixture of acetone and butanone instead of only phenol and acetone in the original. [9] Both liquid-phase oxidation of heavy naphtha and the Fischer–Tropsch reaction produce mixed oxygenate streams, from which 2-butanone is extracted by fractionation. [10]
