Avobenzone (Avobezone) is A synthetic UV absorber, is a good UV-A(> 320nm) type UV absorber, can block the full band (320 ~ Chemicalbook400nm) UVA, is an efficient broad-spectrum oil-soluble UVA filter, combined with other UVB sunscreen, Provides full UVA and UVB protection against photogenic skin cancer
At present, the main methods of synthesis of Avobenzone are: (1) condensation addition and water elimination method, that is, p-methoxyacetophenone and p-tert-butylbenzaldehyde through condensation, bromine addition, elimination into acetylene, hydration to obtain products, the yield is 58%, the method has a long route, high cost, low yield; (2) Claisen ester reduction method, that is, the reaction of p-methoxychemicalbook acetophenone with p-tert-butylbenzoate, the yield is 63.6%, which is low in cost and easy to operate, but the yield is low; ③ Aldehyde-ketone condensation method, that is, condensation of p-methoxyacetophenone and p-tert-butylbenzaldehyde into alcohol, oxidation, the yield is 34.6%, the method is easy to operate, high cost, low yield.
