Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
Phenylglyoxal was first prepared by thermal decomposition of the sulfite derivative of the oxime: [5]. C 6 H 5 C(O)CH(NOSO 2 H) + 2 H 2 O → C 6 H 5 C(O)CHO + NH 4 HSO 4. More conveniently, it can be prepared from methyl benzoate by reaction with KCH 2 S(O)CH 3 to give PhC(O)CH(SCH 3)(OH), which is oxidized with copper(II) acetate. [6]
It is a colourless liquid that is insoluble in water. Ethyl methylphenylglycidate is usually prepared by the condensation of acetophenone and the ethyl ester of monochloroacetic acid in the presence of a base , in a reaction known as the Darzens condensation .
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone.It is a useful building block in organic chemistry.Apart from that, it has been historically used as a riot control agent, where it is designated CN. [5]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Chalcone is usually prepared by an aldol condensation between benzaldehyde and acetophenone. [ 6 ] This reaction, which can be carried out without any solvent, is so reliable that it is often given as an example of green chemistry in undergraduate education.
2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator, which is used to initialize radical polymerization e.g. in the preparation of acrylate polymers. [1] Under the influence of light the molecule will form radicals which initiate the radical polymerization. It can also be used as an initiator in the process of making an integrated circuit.
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
