Abstract
1,4-bis(imidazol-1-yl)butane was synthesized with tetrabutyl ammonium hydroxide as phase transfer catalyst.By single factor experiments,favorable synthesis conditions of this product were determined.The results show that favorable synthesis conditions are as follow: concentration of potassium hydroxide is 90%,dosage of catalyst is 0.3 mmol,reaction temperature is 60 °C,molar ratio of reactants is 2.2 and reaction time is 6 h.At last,the product was characterized by nuclear magnetic resonance and infrared spectra.
