Boron-containing aluminium silicates having a zeolitic structure, process for producing the same and their use.

摘要

Boron-containing aluminosilicates with a zeolite structure are prepared by mixing silicon compounds, aluminium compounds, boron compounds, sodium compounds, potassium compounds and choline compounds and water in specified relative amounts and heating the mixture in a sealed vessel. The boron-containing aluminosilicates are used as catalysts in the preparation of hydrocarbons, in particular C2- to C4-olefins, from methanol.
