Synthesis of a New Type Perfume fraistone Catalyzed by Heteropoly Acids(salt) |
LIU Jie feng etc.(Maoming college; Guangdong maoming 525000; China) |
Abstract:Fraistone was synthesized with reaction of Ehyl Acetyl acetate and 1,2 Propanediol, by aluminnm silicolungstie as catatlyst. The optimum conditions are follows: the ratio of ethyl acetate, 1,2 Propanediol, Cyclohexane,Aluminnm Silicolungstie is 0.2?mol:0.2?mol:40?ml:0.3?g, reaction for 3.5 hours.The yield reaches 81.6%. The product was characterized by the physical and chemical character, and spectra. |
Key words:fraistone; heteropoly acids; synthesis |
