벤조페논-2 C화학적 특성, 용도, 생산
화학적 성질
yellow to brown crystalline powder용도
2,2',4,4'-Tetrahydroxybenzophenone is a uV-absorber that helps protect against product degradation because of uV-light exposure. It can also mask odor associated with a formulation’s composition.제조 방법
Obtained (small amount) by melting a fluorescin chloride/sodium hydroxide mixture in the presence of a very few water at 230–240° for 2–3 h.색상 색인 번호
BZP-2 is widely used in perfumes to prevent their degradation due to light. It can cause allergic contact dermatitis.Safety Profile
Moderately toxic by ingestion. Aneye irritant. Mutation data reported. When heated todecomposition it emits toxic fumes of NOx.Synthesis
2 mol of resorcinol dimethyl ether is added dropwise to a mixture of 1 mol of phosgene and 1 mol of aluminum chloride, and the mixture is heated to 65-80° C at a temperature of 30-40° C in the presence of a chlorinated hydrocarbon selected from aliphatic and aromatic chlorides, such as ethylene dichloride. It is then cooled to 40° C, 2 to 3 mol of aluminum chloride are added, the mixture is heated to 60-70° C, dilute hydrochloric acid is treated with aqueous sodium hydroxide solution, and 2,2',4,4'-Tetrahydroxybenzophenone is isolated by filtration.벤조페논-2 준비 용품 및 원자재
