| 外観 | 白色～黄色～緑色粉末～結晶 | | 定義 | 本品は、次の化学式で表される有機化合物である。 | | 化粧品の成分用途 | 褪色防止剤 | | 説明 | Phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide can be used as a photoinitiator for: Radical polymerization of dental resins. It enhances the polymerization rate and conversion compared to other initiators. It is a polymer-based ceramic material modified with divinylbenzene for the preparation of high-temperature sensor applications. | | 使用 | Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide is a useful research chemical compound. | | 使用 | Versatile UV photoinitiator for radical polymerization of unsaturated resins, especially pigmented formulations. | | 製造方法 | Under nitrogen protection and room temperature, 1.4 g of zinc powder was added to the 100 mL reaction flask with stirring.15 ml of ethyl acetate, 4.1 g of 2,4,6-trimethyl benzoyl chloride, and a solution of 2.5 g of phenylphosphorus dichloride in 5 ml of ethyl acetate was added dropwise to the mixture. After that, the temperature was continued for 2 hours. After the completion of the reaction, 20 mL of water and 1.5 mL of 30% hydrogen peroxide were respectively added to the system, and the reaction was continued for half an hour. Saturated sodium bicarbonate solution was added to neutralize weakly alkaline. Finally, Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide was obtained after purification.
 | | 定義 | Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (PPO) has a local absorption maximum in the visible spectrum at 405 nm and could provide sufficient initiating radicals to crosslink polyamic diacrylate ester in NMP[1]. Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (GR-XBPO) could be used as the reductant, and Monoethanolamine as the oxygen inhibition agent. After UV irradiation, oxygen-containing groups (OCGs) on the graphene oxide (GO) plane and edges are largely removed due to the reduction of GO by free radicals generated by photoinitiator decomposition[2]. | | 参考文献 | [1] Maruti Hegde. “3D Printing All-Aromatic Polyimides using Mask-Projection Stereolithography: Processing the Nonprocessable.” Advanced Materials 29 31 (2017).

Photoinitiator 819 (HRcure-819) can also be used in colored UV-curable plastic coatings. UV coatings have been widely used on plastic shells of various electronic and household appliances due to their excellent performance and efficient production. However, the deep curing of UV coatings after coloring is not good, resulting in poor film adhesion and poor dispersion and arrangement of pigments by UV resins, which seriously affect the appearance of the coatings. Therefore, the traditional construction process is to paint solvent-based colored primer first; after baking, apply UV varnish to improve the physical properties of the film surface.
