Abstract
The reaction of titanyl (Ti=O) groups with SO2, which for molecular ti tanyl complexes is found to occur readily at room temperature, has bee n used to test for the presence of titanyl groups in titanium silicali te (TS-1) and Ti-MCM-41. Exposure of samples to SO2 does not lead to a ny reduction in the intensity of the characteristic IR band observed a t 960 cm(-1) implying that this absorption is not associated with the presence of titanyl groups.
