“…Titanium silicate 1 (TS-1) is an efficient catalyst for the selective oxidation of hydrocarbons (Baerlocher, McCusker, & Olson, 2007;Kielcev, 1980;Taramasso, Perego, & Notari, 1983;Thangaraj, Kumar, Mirajkar, & Ratnasamy, 1991;Thomas & Raja, 2006). It can be applied to the epoxidation of olefins (Clerici, Bellussi, & Romano, 1991;Tatsumi, Nakamura, Yuasa, & Tominaga, 1991;Wang, Mi, Wang, & Wang, 2005), the oxidation of alcohols to form aldehydes and ketones (Clerici & Bellussi, 1992;Esposito, Neri, & Buonomo, 1984), and the hydroxylation of phenols and other aromatic compounds (Kooyman et al, 1992;. Moreover, a global-scale hydrogen peroxide-to-propylene oxide (HPPO) process based on TS-1 is scheduled for commercialisation.…”
