| Abstract: | Ethyl-dibenzoylmethane,which is one of the good light absorbents,was synthesized by using benzoyl acetate and ethyl phenyl ketone as their original raw materials,dibenzoylmethane was obtained through Claisen condensation,and then ethyl-dibenzoylmethane was got by alkylation.The structure of the products was analyzed and characterized by UV-absorbent,et al. |
