p-acdophenyl trimethyl ammonium iodide was synthesized with p-dimethyamino acetophenone and methyl io-dide in ethyl acetate solution.The structure was characterized by infrared spectroscopy and nuclear magnetic resonance spec-troscopy.The effect of reaction conditions on the yield was investigated.The results showed that in ethyl acetate solution, when the methyl iodide was used by an excess of 50%,the resulting product will precipitate out of the solution.When the re-action time lasts for 4 hours,the yield can reach 85%.
