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:
Then, the mixture is continuously stirred until the polymer dissolves and a gel gradually forms. [3] The gel is allowed to settle for one to two days before the final consistency of the gel can be reached. [5] The exact method of preparing gels depends on the properties of the formulation ingredients.
First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.
The reaction of acetophenone enolate with phenyl isothiocyanate. In this one-pot synthesis [9] the ultimate reaction product is a Thiazolidine. This reaction is stereoselective with the formation of the Z-isomer only. Electrochemical reduction gives thioformamides. [10]: 340
An upturned vial of hair gel Silica gel. A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. [1] [2] Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady state, although the liquid phase may still diffuse through this system.
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.
A container with cream. Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons, waxes, or polyethylene glycols as the vehicle for external skin application.

The initial product is a thioamide for example that of acetophenone [7] which can again be hydrolyzed to the amide. The reaction is named after Karl Kindler The Kindler modification of the Willgerodt rearrangement. A possible reaction mechanism for the Kindler variation is depicted below: [8]
