Abstract

Shaped body comprising an aluminosilicate and aluminum oxide, wherein the shaped body has a molar Al/Si ratio in the range from 10 to 30 and an at least bimodal pore distribution for pores having a diameter of greater than 1 nm, with the volume of the pores of the shaped body having a diameter of greater than 10 nm corresponding to at least 40% of the total pore volume of the shaped body, process for producing it and process for the continuous preparation of methylamines by reaction of methanol and/or dimethyl ether with ammonia in the presence of a heterogeneous catalyst, wherein the abovementioned shaped bodies are used as catalyst.
