6M-IMMEDIATE Research Report: Preparation of Pt on Carbon Black Supported Catalysts
Kaluža, Luděk; Zdražil, Miroslav; Gulková, Daniela; Vít, Zdeněk; Šolcová, Olga; Soukup, Karel; Maixnerová, Lucie
2013 - anglický The purpose of the present work is to elucidate on carbon black materials as a support for high loading of Pt in highly dispersed form. There are three main methodologies described in the .literature for deposition of Pt: i) impregnation of the support with solution of well soluble Pt precursors, ii) deposition of a colloidal form of Pt onto the support, and iii) deposition of Pt onto the supports from microemulsion of Pt precursor with the assistance of surfactant. The Pt containing species are deposited either by spontaneous adsorption or by evaporation of the solvent. The deposited platinum compound is transformed to metallic platinum with some chemical or physical (temperature) treatment. Remainders of the deposited compound other than platinum must be removed from the catalysts (for instance by washing, calcination, etc.).

WP5 Status Report Months 31 to 50
Křišťál, Jiří; Stavárek, Petr; Jiřičný, Vladimír
2013 - anglický Within WP5 in this reporting period focused on the development of a new intensified reactor concept for sulph(on)ation reaction. Based on the previous hydrodynamic experiments and mathematical models we designed a new reactor – microSulphonator. We also constructed and manufactured several prototypes that were later tested with model fluids. Experimental data were used for the validation of the models defined previously. Results of this period served as a basis for the final microSulphonators to be tested in the PGB pilot plant during the demonstration phase of the F3 project.

Exploration of 9-Bromo[7]helicene Reactivity
Žádný, Jaroslav; Jakubec, Martin; Velíšek, Petr; Sýkora, Jan; Storch, Jan
2012 - anglický Our new microwave assisted photodehydrocyclisation and completely reviewed synthetic approach for a multi-gram scale production of 9-bromo-[7]helicene led us to explore the reactivity of this compound mainly in Pd-catalysed reactions and to the further functionalization of this molecule. Next to other transformations, palladium catalysed carbon – heteroatom coupling reactions provide a large portfolio of racemic helicenes bearing different functional groups in good to excellent yields. Many of the reactions are performed in the microwave initiator saving reaction time to a minimum comparing with conventional and known synthetic methods. Such prepared compounds can undergo further synthetic reactions or can be used on a field of molecular electronics, surface chemistry or in other applications. The separation of racemic mixtures is under running in our lab. Optically pure compounds of such a type can open new possibilities in their use.
