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.
