Abstract

The reaction of titanyl (Ti=O) groups with SO₂, which for molecular titanyl complexes is found to occur readily at room temperature, has been used to test for the presence of titanyl groups in titanium silicalite (TS- I) and Ti-MCM-41. Exposure of samples to SO₂ does not lead to any reduction in the intensity of the characteristic IR band observed at 960 cm^- ¹, implying that this absorption is not associated with the presence of titanyl groups.
