Prepn. of methyl amines by reacting methanol and/or dimethyl ether with ammonia at 350-450 deg.C and at atmos. pressure or 20-50 atm. is claimed. - The improvement comprises carrying out the reaction, opt. in the presence of 1 mole pure H2 or synthesis qas contg. at least 80 vol% H2 per mole methanol and/or dimethyl ether, in the presence of an activated catalyst (I) using a square velocity of 1-6.5. - Specifically, (I) contains gamma or kappa alumina, 0.05-1.5 (pref. 0.2-0.8)% Fe2O3 and/or 0.05-15 (pref. 0.2-0.8%) TiO2 and has a pore vol. of 0.01-0.09 (pref. 0.02-0.06) Cm3/g. |
