24-P-29-Pt-2,2′bipyridine complex encapsulated in Y zeolite-catalysts for ethylene selective dimerization

Publisher Summary This chapter presents results concerning the synthesis of Pt(2,2’-bipyridine)Cl 2 (K) encapsulated in Y zeolite and its activity in ethylene (C 2 H 4 ) selective dimerization to linear butenes. Diffuse reflectance ultraviolet-visible (UV-VIS) spectroscopy and Fourier transform infrared spectroscopy (FTIR) are used to investigate the state of the complex encapsulation. The influence of the reaction parameters on C 2 H 4 selective dimerization to linear butenes is studied, and it is concluded that Pt(2,2’-bipyridine)Cl 2 encapsulated in Y zeolite is a selective catalyst for ethylene dimerization to linear butenes at low temperatures (80–150°C) and a reactant flow rate corresponding toWHSV 2h -1 .
