Study on the New-type Catalyst in Preparing Methylamines
Mao Yaohua Wang Yuanji Huang Zuyi Zhong Qiling Xu Jingshi
The rare-earth mordenite made by ourselves has been used for the catalyst in the gas-phase reaction of preparing methylamines by using amine and methanol. It is of high activity and selectivity for preparing dimmethylamine. The results of experiment(the experimemtal conditions are: the temperature--360～380℃, the space velocity Vspace=6, and the ratio of the molar concentrations[NH_3]/[CH_3OH]=2.) show that the distribution of the products is: monomethylamine(CH_3NH_2)-36.64%, dimethylamine((CH_3)_2NH)-41.86%, and trimethylamine((CH_3)_3N)-23.5%.
