| Abstract: | Taking 3,4,5-trifluoroaniline and acryloyl chloride as raw material and sodium bicarbonate as acid-binding agent,N-(3,4,5-trifluorine)phenyl]acrylamide(TFPA)was synthesized.The chemical structure of product was characterized by means of Fourier transform infrared spectroscopy(FTIR),nuclear magnetic resonance hydrogen spectrum(1 H NMR),nuclear magnetic resonance carbon spectrum(13 C NMR).The effects of material mole ratios,sodium bicarbonate contents,reaction temperature and reaction time on the yield of TFPA were investigated.When the mole ratio of 3,4,5-trifluoroaniline and acryloyl chloride is 1∶1.1,sodium bicarbonate usage is 1.2%of the total feed mass,reaction time is 5 h and reaction temperature is 5℃,the production yield is 74.4%and the best product could be obtained.The function equation of TFPA solubility with temperature in ethanol solvent is obtained,and the fitting correlation is 0.999.The established temperature dependence model of solubility provides theoretical guidance for TFPA purification process. |
