Usage

Uses

Used in Plastics Industry:
4,4'-BIS(METHYLAMINO)BENZOPHENONE is used as a UV stabilizer for plastics to prevent degradation and discoloration caused by exposure to sunlight or other UV sources, thereby enhancing the durability and longevity of plastic products.
Used in Adhesives Industry:
In the adhesives industry, 4,4'-BIS(METHYLAMINO)BENZOPHENONE serves as a UV stabilizer, ensuring the stability and performance of adhesives when exposed to UV radiation, which is crucial for maintaining the bond strength and integrity of the adhesive.
Used in Coatings Industry:
4,4'-BIS(METHYLAMINO)BENZOPHENONE is used as a UV stabilizer in coatings to protect the coated surfaces from UV-induced degradation, such as chalking, fading, or loss of gloss, thus maintaining the aesthetic and functional properties of the coatings.
Used in Inks and Photoresist Formulations:
4,4'-BIS(METHYLAMINO)BENZOPHENONE is used as a photoinitiator in the production of inks and photoresist formulations, playing a crucial role in the curing process by initiating the polymerization reaction upon exposure to UV light.
Used in Skincare Products:
4,4'-BIS(METHYLAMINO)BENZOPHENONE is used as a photoprotective and antioxidant ingredient in skincare products, providing protection against harmful UV radiation and preventing skin damage, such as premature aging, sunburn, or skin cancer.
It is important to handle 4,4'-BIS(METHYLAMINO)BENZOPHENONE with care, as it may pose health risks if not used appropriately. Proper safety measures should be taken during its application to ensure the well-being of both the users and the environment.

Acetic Acid Accelerated Visible-Light Photoredox Catalyzed N-Demethylation of N,N-Dimethylaminophenyl Derivatives

N,N-Dimethylaminophenyl moiety is a common fragment in medicinal chemistry as several pharmaceuticals bearing this privileged motif are on the market and under clinical evaluation. Oxidative N-demethylation is generally regarded as the major metabolic pathway. However, pharmacokinetics, metabolites studies as well as the further structural modification are precluded by the impracticality of chemical synthesis. Here we report that acetic acid can significantly accelerate visible-light photoredox catalyzed N-demethylation of N,N-dimethylaminophenyl derivatives. This approach is easy for large scale reaction and even for potential industrial manufacture. (Figure presented.).

A series of BiO: XIy/GO photocatalysts: Synthesis, characterization, activity, and mechanism

A series of bismuth oxyiodide (BiOxIy)-grafted graphene oxide (GO) sheets with different GO contents were synthesized through a simple hydrothermal method. This is the first report where four composites of BiOI/GO, Bi4O5I2/GO, Bi7O9I3/GO, and Bi5O7I/GO have been characterized using X-ray diffraction, transmission electron microscopy, scanning electron microscopy energy-dispersive spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and diffuse reflectance spectroscopy. The assembled BiOxIy/GO composites exhibited excellent photocatalytic activities in the degradation of crystal violet (CV) under visible light irradiation. The order of rate constants was as follows: Bi7O9I3/GO > Bi4O5I2/GO > Bi4O5I2 > Bi7O9I3 > Bi5O7I/GO > BiOI/GO > BiOI > Bi5O7I > GO. The photocatalytic activity of the Bi7O9I3/GO (or Bi4O5I2/GO) composite reached a maximum rate constant of 0.351 (or 0.322) h-1, which was 1.8 (or 1.7) times higher than that of Bi7O9I3 (or Bi4O5I2), 6-7 times higher than that of BiOI/GO, and 119-130 times higher than that of BiOI. The quenching effects of different scavengers and electron paramagnetic resonance demonstrated that the superoxide radical (O2-) played a major role and holes (h+) and hydroxyl radicals (OH) played a minor role as active species in the degradation of crystal violet (CV) and salicylic acid (SA). Possible photodegradation mechanisms are proposed and discussed in this research.

Photocatalytic degradation of michler's ketone in water by Uv light illumination using TiO2 photocatalyst: Identification of intermediates and the reaction pathway

The TiO2/UV photocatalytic degradation ofMichler's Ketone (MK) has been investigated in aqueous heterogeneous suspensions. Results obtained show rapid and complete oxidation of MK after 24-h, and more than 97.5% of MK was mineralized after a 32-h exposure
