A series of rhenium complexes bearing a pyridine-based PNP-type pincer ligand are synthesized from phosphine as precursors. dinitrogen-bridged dirhenium complex the ligands catalytically converts dinitrogen into ammonia during reaction with KC8 reductant and [HPCy3]BArF4 (Cy=cyclohexyl, ArF=3,5-(CF3)2C6H3) proton source at ?78 °C to afford 8.4 equiv based on atom catalyst. The rhenium-dinitroge...

Black garlic is a traditional spice having potential of herbal medicine; however, continuous heating darkens its color and changes taste due to chemical processes new equilibrium in the system. In this study, fresh was processed into black at 60 °C for 24 days. Changes physical parameters, such as browning protein content, reducing sugar antioxidative components were recorded. Protein content m...

In the work, composition of starting materials and reaction products was checked by chromatographic method. The purpose work is to study effect temperature on decomposition process propane-butane mixture at high temperatures. Qualitative analysis carried out method "witnesses", quantitative internal normalization. Spatial performed a DRON- 4.0 (CuKa - radiation) diffractometer, particle size sc...
