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.
