Inhalation Risk:Evaporation at 20 °C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short Term Exposure:The substance is mildly irritating to the skin.
Effects of Long Term Exposure:The substance may have effects on the liver and kidneys, resulting in impaired functions. Tumours have been detected in experimental animals but may not be relevant to humans.
Detailed Introduction
Benzophenone 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 ℃.
Application
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. Uses for photosensitive resins, coatings and adhesives. 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. 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. 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. It is light initiator for UV products, pharmaceutical intermediates, fragrances, light stabilizers etc. It is light pigment, medicine, perfume, pesticides intermediates, it can also be used for UV-curable resins, inks and coatings initiator. Benzophenone is used as a synthetic intermediate for manufacture of pharmaceuticals and agricultural chemicals. It is also used as a photoinitiator in UV-curable printing inks, as a fragrance in perfumes, as a flavor enhancer in foods. Benzophenone can be added as a UV-absorbing agent to plastics, lacquers, and coatings at concentrations of 2–8%.
