| Abstract: | An environmental friendly catalyst, phosphotungstic Acid Supported on Active Carbon, was prepared. Fraistone was synthesized from 1,2-propanediol and ethyl acetoacetate in the presence of H3PW12O40/C. The yield of fraistone was 84.8 % under suitable reaction conditions of the molar ratio of 1,2-propanediol to ethyl acetoacetate 1.5:1,the loading amount of H3PW12O40/C 23.1 %, the mass percent of H3PW12O40/C to the reactants 1.0 %, and the reaction time 120 min. Fraistone was confirmed by infrared spectrum, mass spectrum and elementary analysis. |
