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。
This paper reports the gas phase methylation of aniline and methanol on a modified ZSM-5 zeolite catalyst. The results showed that the selectivity to DMA of the modified ZSM-5 catalyst was 88.5 at liquid hourly space velocity of 1.0 h ~ (-1) and aniline / methanol molar ratio of 1/3 at 300 ℃ and atmospheric pressure %, Aniline conversion 97.8%. This result has obvious application prospects.
