SILICON-TITANIUM MIXED OXIDE-CONTAINING DISPERSION FOR THE PRODUCTION OF TITANIUM-CONTAINING ZEOLITES
摘要:
Dispersion containing pyrogenic silicon-titanium mixed oxide powders with a silicon dioxide content of 75 to 99.99 wt.-% and a titanium dioxide content of 0.01 to 25 wt. %, water and a basic, quaternary ammonium compound, wherein the mean aggregate diameter of the particles of the silicon-titanium mixed oxide powder in the dispersion is 200 nm at most. Process for the production of a titanium-containing zeolite with the use of the dispersion.
