（E） -3- （2- furyl）propenoic acid was synthesized by making use of phase transfer catalysis （PTC） in the existence of potassium acetate and both 2 - furyl methanal and diacetyl oxide as raw material. Its structure characterized by UV, IR and X- ray single crystal diffraction. Molecular formula and formula weight of target compound that synthesized were C7H6O3 and 138.12 respectively. The crystal belongs to monoclinic system and C2/c space group. Unit cell is： a = 18. 993 （6） A, b = 3. 8474 （12） A, c = 20. 095 （6） A, α = 90.00°β = 114. 054° （4）, γ = 90.00°, V= 1341.0 （7）nm^3, Z = 8, Dr = 1. 368 Mg/cm^3, F（000） = 576,μ （MoK ／ a） = 0. 71073. The structure was given by direct method. Final deviate factor was R1 = 0. 0645 and wR2 = 0. 1360. Laminar compound was formed by intermolecular weak interaction.
