高聚物负载季铵盐三相相转移催化剂合成对硝基苯甲醚的研究

STUDY ON SYNTHESIS OF pNITROANISOLE IN PRESENCE OF POLYMERSUPPORTED QUATERNARY AMMONIUM SALTS TRIPHASETRANSFER CATALYST

合成了不同种类的高分子聚合物负载季铵型三相相转移催化剂 ,用于合成对硝基苯甲醚。考察了氢氧化钠用量与浓度 ,反应温度 ,不同季铵基种类等因素对三相相转移催化反应的影响 。

A series of polymersupported quaternary ammoniumsalts triphase transfer catalysts were synthedized and used as catalysts in the synthesis of pnitroanisole. The effect of reaction parameters, such as reaction temperature, the ammount and the concerntration of NaOH aqueous solution and the difference kinds of quaternary ammonium radical was studied and discussed.
