| Abstract: | 2,2]-paracyclophane has been synthesized by the method of Hofmann elimination with quaternary ammonium salt as raw materials.The structure of synthesized product was characterized by IR,HNMR as well as melt peint test.Synthetic process was optimized by orthogonal experiment and best technology parameters were the concentration of quaternary ammonium salt 220.0 g/L,NaOH 240.0 g/L,reaction temperature 110℃ and reaction time 10h.The yield of 35.2 was reached with best technology parameters.The yield obtained by our method is 10 and is much higher than other methods. |
