Synthesis And Characterization Of 4-(2-Hydroxyphenoxy) Phthalic Nitrile

4-(2-hydroxyphenoxy) phthalic nitrile was prepared by the nucleophilic substitution reaction of catechol and 4-nitro phthalic nitrile in DMF with the existence of N-2 and K2CO3. The optimal reaction conditions were obtained as follows: the mole ratio of catechol, K2CO3 and 4-nitro phthalic nitrile is 2: 1: 1, with the quality of the solute concentration of 0.222g/mL and reaction temperature 80 degrees C. Consequently, the yield of final product reached 87.64%, and the structure of the 4-(2-hydroxyphenoxy) phthalic nitrile was characterized by IR, H-1 NMR and DSC.
