Two phenyl ketone use and synthesis method

Summary two benzophenone is colorless prismatic crystal with sweet and rose flavor, melting point 47-49 degrees C, relative density of 1.1146, refractive index of 1.6077. Soluble in ethanol, ether, chloroform and other organic solvents and monomers, insoluble in water. It is a free radical photoinitiator, which is mainly used in free radical UV curing system, such as coating, printing ink, adhesive and so on. In the pharmaceutical industry is mainly used in the production of bicyclic piperidine, benzoyl hydrobromide. This product is also a kind of styrene polymerization inhibitor and perfume fixative, which can be used in perfumes and soaps. Products in the storage and transportation process should pay attention to moisture, sunscreen, away from the heat source, the temperature should not exceed 45 degrees C.

Two the application of sunscreen in the field of sunscreen cosmetics is a new hot spot in the field of cosmetics, almost all of the sunscreen products on the market contain two benzophenone compounds. Two benzophenone compounds can protect the skin from injury, commonly used to produce high products. In recent years, the consumption of two benzophenone in cosmetics has been increasing. Recent studies have shown that fluorescence is also a harmful UV light source, so the application of two benzophenone in the field of cosmetics has been expanded, has been extended to hair conditioner, lotion and lipstick, etc.. In addition, it is also a flavoring agent, which can be used in many perfumes and soaps.

Banana Boat company developed a UVA UV absorption technology called AvoTriplex, this technology is based on two benzophenone, add stabilizer to prevent the decomposition of two benzophenone in the sun. In addition, a reinforcing agent is added in the formula, and the stabilizer can play a synergistic role so as to achieve the optimization of the sunscreen ability of two phenyl ketone.

High molecular weight two benzophenone photoinitiator synthesis and kinetic study of agent 4- two hydroxy benzophenone (HBP), toluene diisocyanate (TDI) -2,4-, 4,4 '- two hydroxy two benzophenone (DHBP) as raw material, through two steps, a high molecular weight two benzophenone light initiator synthesis HBP-TDI-DHBP-TDI-HBP (HTDTH). The polymerization kinetics of HTDTH was studied by real-time infrared light. The results show that HTDTH is an effective photoinitiator. Using HTDTH/ amine light initiator system two three glycol reduction two acrylate (TPGDA) polymerization, with amine and lead to increase agent concentration, the reaction rate (Rp) and monomer conversion rate (P) increased at the same time.

Anhydrous two benzophenone as indicator indicator is widely used in the synthesis experiments, can be used as a treatment of toluene, benzene, THF and acetonitrile indicator; after adding if there is a beautiful blue, you can use the best preserved in the distillation, sodium, but why to form a blue color, there is a lot of argument, Mo Zongyi the world is not the same.

Now from the reaction mechanism of the books abroad on its reason: excerpts translated into Chinese might mean: "radical anion called carbonyl radical generated by ketone, benzophenone as indicator is two oxygen atoms in two benzophenone captured electron in sodium, the formation of dark blue carbonyl radical the free radical; in stereo, electric
