Benzophenone Usage And Synthesis
descriptionBenzophenone appears as colorless prismatic crystals, with sweetness and aroma of roses, melting point is 47-49 ℃, the relative density is 1.1146, refractive index is 1.6077. It is soluble in alcohol, ether, chloroform and other organic solvents and monomers, insoluble in water. It is a free radical photoinitiator, are mainly used in free radical UV curing systems , such as coatings, inks, adhesives and so on, and also used as the intermediates of organic pigments, pharmaceuticals, perfume, and insecticide . In the pharmaceutical industry, it is mainly used for the production of bicyclic Piperidine Benztropine hydrobromide, diphenhydramine hydrochloride. This product is styrene polymerization inhibitor and perfume fixative agent, to impart a sweet flavor with spices, widely used in the perfume and soap flavor. Attentions should be paid to the products to prevent moisture, sun , heat in the storage and transportation process, the temperature should not exceed 45 ℃.
The above information is edited by the Chemicalbook of Tian Ye.
Chemical PropertiesShiny white prismatic crystals with a sweet taste, smell like a rose, melting point is 47-49 ℃, boiling point is 306 ℃, insoluble in water, soluble in alcohol, ether and chloroform.
applicationSunscreen cosmetics is the hot new products of cosmetics, almost all sunscreens contain benzophenone compound on the current market. Benzophenone compounds that protect the skin from harm, often is used to produce high product. In recent years, the cosmetics consumption of benzophenone grows continuesly. Recent studies suggest that fluorescence is also a harmful ultraviolet light source, so benzophenone expands the range of applications in the field of cosmetics, it has been extended to hair conditioners, lotions and lipsticks. In addition, the perfume fixative agent also can give spice sweet flavor, is used in many perfumes and soap flavor.
Banana Boat company has developed a UVA ultraviolet-absorbing technology called AvoTriplex, which is benzophenone-based, adding a stabilizer to prevent the benzophenone from breaking down in the sun. Enhancer is also added into the formula, and stabilizer may act synergistically, to optimize benzophenone sunscreen capacity.
  1. Benzophenone Mainly used for the preparation of vanilla, butter and other flavor,It can be used as a fixative agent. Its weak sweet bay leaves fragrant , can be widely used in low-grade flavors, such as roses, bay leaves, sweet curd, shy flower, lily of the valley, sunflower, orchid, hawthorn flowers, incense and Wei Oriental flavor and other flavors. It is also used as an antioxidant in soaps, and occasionally used for almonds, berries, fruit, butter, nuts, peaches, vanilla beans and other food flavors in trace amount.
  2. Uses for photosensitive resins, coatings and adhesives.
  3. Benzophenone is an intermediate of UV absorbers, organic pigments, pharmaceuticals, perfume, insecticide . It is used for the production of bicyclic Piperidine Benztropine hydrobromide, diphenhydramine hydrochloride in the pharmaceutical industry . The product itself is a styrene polymerization inhibitor and a perfume fixative. Giving sweet taste to flavors, it is used in many perfumes and soap flavors.
  4. It is commonly used in soap flavor, used in ultraviolet absorbers, pigments, pharmaceuticals and reagents production, and also is low temperature fast curing agent for fluorine rubber. It serves to manufacturers to package the product in clear glass or plastic.
  5. Benzophenone is widely employed as a photo initiator in UV-curing applications such as inks, imaging and clear coatings in the printing industry. It acts as a UV blocker to prevent photo-degradation of the packaging polymers or its contents.
  6. It is light initiator for UV products, pharmaceutical intermediates, fragrances, light stabilizers etc.
  7. It is light pigment, medicine, perfume, pesticides intermediates, it can also be used for UV-curable resins, inks and coatings initiator.
indicatorBenzophenone is widely used in the synthesis experiment as an indicator, it can be used as a indicator while handling toluene, benzene, THF, acetonitrile ect.; if there is a beautiful blue after added, it can be distillated and used, it is the best to kept in sodium, but the reason of generating blue is still a puzzle.
Here is the reason from a foreign book about reactions mechanism : 'a radical anion generated by the one called carbonyl radical, benzophenone acts as the indicator is that benzophenone oxygen atoms in sodium capture electrons to generate dark blue carbonyl radical; the radicals perspective on the electrical aspect is stable, mainly used to indicate 'anaerobic conditions',Widely used.
After the addition of benzophenone, more blue of the solution, indicating less oxygen in the solution, indirectly instructing the little water. However, whether the solution turns blue, is related to the added amount of benzophenone and processing solvent, THF (300ml) contains lots of water, and needs more than about 6 hours to reflux, and of course, it is related to the amount of processing solvent, the more the longer, toluene , benzene and other samples containing less aqueous need less reflux time, it is best to add the common desiccants to pretreat, such as: potassium carbonate, sodium sulfate, sodium hydroxide, etc., so that the processing time will be shortened.

Production methodThere are different methods. 1. Condensation of benzyl chloride and benzene , and then by nitric acid oxidation. 2. The condensation of benzene and carbon tetrachloride, and then by hydrolysis. In the laboratory, the production is based on aluminum chloride as a catalyst, prepared by reacting benzene with benzoyl chloride.3.Condensation of benzene and benzoyl chloride in the presence of aluminum chloride, and then crystallized from ethanol.
Chemical PropertiesOrange Crystals
Chemical PropertiesBenzophenone is a combustible, white, crystalline solid with a rose-like odor
UsesIt is used in the manufacturing of antihistamines, hypnotics, insecticides.
UsesReported to bind monsaccharides in the presence of polysaccharides
General DescriptionWhite solid with a flowery odor. May float or sink in water.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileKetones, such as Benzophenone, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Benzophenone can react with oxidizing materials.
Health HazardIngestion causes gastrointestinal disturbances. Contact causes eye irritation and, if prolonged, irritation of skin.
Fire HazardFlash point data for Benzophenone are not available, but Benzophenone is probably combustible.
Contact allergensUnsubstituted benzophenone is largely used in chemical applications. It acts as a marker for photoallergy to ketoprofen.
Potential ExposureBenzophenone is used in UV curing of inks and coatings; as an intermediate; as an odor fixative in fragrances, flavoring, soaps; in the manufacture of pharmaceuticals and insecticides; in organic syntheses.
