This paper reviews several important issues related with industrial application of catalysts based on titanium silicalite-1 (TS-1). The catalyst preparation has been discussed, especially considering the most critical parameters for industrial application. Two processes already demonstrated on industrial scale (phenol hydroxylation and cyclohexanone ammoximation), and a process, under development by several industrial groups (propylene epoxidation), have been reported and discussed. The possibility to insert titanium in large pore zeolites, in order to widen the application field of this kind of materials, has been considered and the behaviour of several new materials has been reported and compared with the catalytic properties of TS-1.
