Ziegler-Natta catalysts for propylene polymerization – Interaction of an external donor with the catalyst
The interaction of the external donor (propyltrimethoxysilane - PTMS) with titanium-magnesium catalysts (TMCs) containing dibutylphthalate (DBP) as internal donor, which were prepared in different ways, was studied by chemical analysis and infrared diffuse reflectance spectroscopy (DRIFTS). The chemical composition of the catalysts after their interaction with heptane solutions of PTMS, PTMS/Al...
متن کاملNew catalysts for carboxylation of propylene glycol to propylene carbonate via high-throughput screening.
High throughput methodologies screened 81 different metal salts and metal salt combinations as catalysts for the carboxylation of propylene glycol to propylene carbonate, as compared to a 5 mol% Zn(OAc)2/p-chlorobenzene sulfonic acid benchmark catalyst. The reactions were run with added acetonitrile (MeCN) as a chemical water trap. Two new catalysts were thereby discovered, zinc trifluoromethan...
متن کاملBulk Structural Investigation of the Reduction of MoO3 with Propeneand the Oxidation of MoO2 with Oxygen
Reduction of MoO3 in propene and oxidation of MoO2 in oxygen are investigated by in situ X-ray diffraction (XRD) and Xray absorption spectroscopy (XAS). Temperature-programmed and isothermal experiments (573–773 K) are performed to elucidate the structural evolution of phases present during the reactions and, in addition, to reveal the solid-state kinetics of the processes involved. During the ...
