Hydroxonium ion H 3O + is proposed to be the active site of bulk HPW and on high-loaded HPW/SiO 2. The hydration reaction proceeds as the direct reaction of gaseous propene molecules with adsorbed hydroxonium ions. The intermediate isopropyl alcohol ions C 3H 7OH 2 + could be stabilized...
The partially dealcoholated adduct has a surface area of 9.1 m2/g and an apparent density of 0.564 g/cm3. 25 g of said adduct are added to 625 ml of TiCl4 while under agitation at 0°C. It is then heated to 100°C in one hour. When the temperature reaches 40°C one adds ...

Solvent is selected from primary alkyl alcohol(s) and its (their) mixture containing isopropyl alkyl ether(s) produced therefrom. Concentration of alcohol(s) in solvent is maintained high enough to dissolve all or most of water fed into hydration process in common liquid stream of solvent and ...
ISOPROPYL ALCOHOLPROPENEZEOLITESA study of the hydration of propene over acidic zeolites shows that the catalytic activities of H-mordenite and stabilised H- (VUS-)Y are determined by their effective Brnsted acidity (i.e. the concentration of acid sites multiplied by their acid strength). For ...
Comparisons with alternative precursors (aluminum isopropoxide, titanium tert-butoxide, and titanium propoxide) and DFT calculations reveal that, for the TTIP precursor, isolated TiO2 sites play a role in the dehydration of off-gassing isopropyl alcohol. The resulting propene then undergoes ...
2-(Methylthio)pentafluoropropene was obtained by dehydrofluorination of methyl 2 H -hexafluoroisopropyl sulfide by the BF 3 路 NEt 3 complex. Its reactivity with respect to allyl alcohol and hexamethyldisilazane was studied. The electrophilicity of 2-(methylthio)penta-fluoropropene was compared with...
