| Abstract: | The synthesis of furanacrylic acid is improved by the fallowing method, After the halofurm reaction and before furanacrylic sodium is acidified,the eccess of hypochlorite have been removed with certain reduction agent of sodium bisulfite. The yield of furanacylic acid is 82% and the yield of furanacrylic and is 55% when acidifing directly. The Purity of product is 95%. After recrystallization the purity of Product is increased to 99.1%.The Product was checked by IR Spectrum.Ms spectrum and elementary analyisis. |
