Abstract

The supported ionic liquid phase (SILP) concept, which included thin films of ionic liquid dispersed onto porous support surfaces, was applied for the gas-phase hydroformylation of but-1-ene catalyzed by Rh-bpp (bpp=biphephos ligand) complexes. The support material silica was carefully pre-treated by a hydrothermal procedure to induce textural changes concerning the pore size. Starting with a mean pore size of 3 nm these could be enlarged by almost a factor of 10 up to 27 nm. Different particle size fractions having the same pore size of 10 +/- 1 nm were investigated regarding the hydroformylation activity. A clear limitation by pore diffusion can be found for particles larger than 500 mu m in diameter. The limitation could be minimized by enlarging the pore size. To support the data, dimensionless numbers and criteria were calculated, including Thiele-modulus, Mears, and Weisz-Prater. All data support the assumption that limitation occurs around 500 mu m particle size if 10 nm pores are present.
