2,2'-Dihydroxy-4-benzophenone Usage And Synthesis |
Chemical Properties | yellow powder |
Uses | ultraviolet screen |
Uses | benzophenone-8 (dioxybenzone) is an FDA-approved sunscreen chemical with uVA-absorption capabilities. It also can protect product degradation arising from uV-light exposure. It has an approved usage level of 3 percent in the united States. |
Preparation | preparation by condensation of salicylic acid and m-phenol. |
General Description | Yellow powder. |
Reactivity Profile | An alcohol and a ketone. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Ketones 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. |
Fire Hazard | Flash point data for 2,2'-Dihydroxy-4-benzophenone are not available. 2,2'-Dihydroxy-4-benzophenone is probably combustible. |
