Effect of support on the hydrogenation activity of nickel and platinum catalysts.

Grzechowiak J. , Szyszka I.

tom Vol. 10, nr 57

95-100

The effect of supports (Al2O3, Al2O3-TiO2, SiO2, SiO2-TiO2 and TiO2) on hydrogenation activity of nickel and platinum catalysts has been studied. The Ni and Pt content of the samples was fixed at 5 wt.% and 0.5 wt.% respectively The deposition of TiO2 on surface of both Al2O3 and SiO2 supports increases hydrogenation activity of the catalysts. A comparison of activity of the Ni/Al2O3-TiO2 and the Ni/SiO2-TiO2 catalysts proved that the SiO2-TiO2 supports are better both for use of nickel and platinum catalysts. Pt/SiO2-TiO2 catalysts exhibited high catalytic activity in the hydrogenation of toluene at lower temperature range.

The method for the synthesis of 3-chloropropyltrichlorosilane based on the hydrosilylation of allyl chloride with trichlorosilane in the presence of an original Pt catalytic system has been worked out. The yield and selectivity of Cl(CH2)3SiCl3 depend on the nature of the catalytic system and several other factors (the mode of substrate addition, reaction procedure, etc.)- The optimum reaction conditions were determined. A successful scale-up of the process under study allowed us to implement it on a pilot scale as the first step of the newly emerging Polish low-tonnage organosilane industry.
