摘要： 本文报道在改性的ZSM-5分子筛催化剂上,苯胺和甲醇的气相甲基化反应。研究发现,在300℃和常压下,液时空速为1.0h-1和苯胺/甲醇摩尔比为1/3的条件下,改性的ZSM-5催化剂对DMA的选择率为88.5%,苯胺转化率为97.8%。此结果有明显的应用前景。

Abstract: The selective synthesis of N,N-dimethylaniline (DMA) from aniline and methanol was studied over modified ZSM-5 zeolite. At 300℃, under an ordinary pressure,LHSV= 1.0h-1,and aniline:methanol = 1:3,the modified ZSM-5 catalyst was found to show 88.5% selectivity for DMAat the conversion level of 97.8% for aniline, indicating obvious applied prospect.
