Catalytic Synthesis of Fructone with Cr-Doped  P-V Heteropolyacid

Abstract

Abstract: Cr-doped bi-capped Keggin P-V heteropolyacid(H₁₃PV₁₂Cr₂O₄₂·21H₂O) was synthesized and used as catalyst for the synthesis of fructone.The effects of reaction conditions were investigated.The product was characterized and analyzed by FT-IR.The most suitable conditions for the reaction are as follows: n(ethyl acetoacetate)/n (glycol) is 1/2,mass ratio of catalyst to reactant 1.0%,reaction temperature 80～104　℃ and reaction time 60 min.Under these conditions,yield of fructone could reach 98.54%,suggesting that H₁₃PV₁₂Cr₂O₄₂·21H₂O is a good catalyst for the catalytic synthesis of fructone.

Key words: fructone, Bi-capped Keggin type heteropolyacid, catalyst
