    en.wikipedia.org/wiki/2,2-Dimethoxy-2-phenylace...

    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.

  3. Photoinitiator - Wikipedia

    en.wikipedia.org/wiki/Photoinitiator

    Irgacure 819 (BAPO Bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide) is a Norrish type photoinitiator used in polymerization processes like two-photon Polymerization. [7] When exposed to light it forms four radicals (2, 3, 5) per decomposed molecule (1), making it highly efficient in initiating polymerization.

    The photoinitiator and any byproducts resulting from its use should be non-toxic. Redox reactions Reduction of hydrogen peroxide or an alkyl hydrogen peroxide by iron (Figure 3). [2] Other reductants such as Cr 2+, V 2+, Ti 3+, Co 2+, and Cu + can be employed in place of ferrous ion in many instances. [1]

  5. Initiation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Initiation_(chemistry)

    In chemistry, initiation is a chemical reaction that triggers one or more secondary reactions. Initiation creates a reactive centre on a molecule which produces a chain reaction. [1]

  6. Photochemical action plots - Wikipedia

    en.wikipedia.org/wiki/Photochemical_action_plots

    Photochemical action plots are a scientific tool used to understand the effects of different wavelengths of light on photochemical reactions.The methodology involves exposing a reaction solution to the same number of photons at varying monochromatic wavelengths, monitoring the conversion or reaction yield of starting materials and/or reaction products.

  7. Photosensitizer - Wikipedia

    en.wikipedia.org/wiki/Photosensitizer

    Photosensitizers absorb light (hν) and transfer the energy from the incident light into another nearby molecule either directly or by a chemical reaction. Upon absorbing photons of radiation from incident light, photosensitizers transform into an excited singlet state.

  8. 2-Aminoacetophenone - Wikipedia

    en.wikipedia.org/wiki/2-Aminoacetophenone

    2-Aminoacetophenone, also known as β-ketophenethylamine, α-desmethylcathinone, or phenacylamine, is a substituted phenethylamine derivative. [ 1 ] [ 2 ] It is the phenethylamine homologue of cathinone (β-ketoamphetamine) and hence is a parent compound of a large number of stimulant and entactogen drugs .

  9. Acetophenone - Wikipedia

    en.wikipedia.org/wiki/Acetophenone

    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:
