Abstract of the disclosure: The invention relates to titanium-containing zeo-lites, a process for their preparation and their use. To prepare these compounds, a mixture of silicon compounds, aluminum compounds, sodium compounds, potassium compounds, choline compounds, water and titanium compounds in speci-fied proportions is prepared, and this mixture is heated in a closed vessel. The zeolites are used as catalysts in the preparation of C2-C4-olefines from methanol. |
