Anna FAJDEK, Agnieszka WRÓBLEWSKA, Eugeniusz MILCHERT - Institute of Organic Chemistry Technology, West Pomeranian University of Technology, Szczecin Please cite as: CHEMIK 2010, 64, 5, xx-xx Glycidol is an epoxy compound with numerous applications. It may be obtained via chlorine or chlorine-free methods. Chloride methods generate a large amount of waste; they are very harmful to the envi- ronment. Chlorine-free methods, using allyl alcohol as an organic raw material, and whose oxidizers include peracids, organic hydroperoxides or hydrogen...

Marian TANIEWSKI Please cite as: CHEMIK 2010, 64, 5, xx-xx The science of science, the philosophy of science, and also the philosophy of chemistry, being an element of the latter, indicate that with time sciences undergo significant changes with regard to the subject of their study, their tools and their tasks. Therefore, the characterisation of a scientific discipline and of its role in spiritual development and civilisation progress of humankind must always be related to a defined...

Magdalena PIĄTKOWSKA - Analytical Laboratory at the Institute for Inorganic Chemistry, Gliwice Please cite as: CHEMIK 2010, 64, 5, xx-xx In modern world many important opinions and decisions depend on the results of chemical analysis. This applies to determination of both macro components, as well as micro components present in trace amounts. These concentrations must remain under strict control. However, the problem of reliability of the results of inorganic trace analysis, despite the use of sophisticated instruments...

Małgorzata ODZIEMKOWSKA – Institute for Fuels and Renewable Energy, Warsaw Please cited as: CHEMIK 2010, 64, 5, xx-xx In Europe, after a long period of dominance in the transport sector gasoline vehicles, increased interest in diesel vehicles is observed. The popularity of diesel engines is due to their high combustion efficiency and reliability. Unfortunately, combustion gas significantly contributes to atmosphere pollution. Emission reduction of soot, nitrogen oxides, particle matter up to the required level, can be achieved...

Anna MATUSZEWSKA – Institute for Fuels and Renewable Energy, Warsaw Please cited as: CHEMIK 2010, 64, 5, xx-xx Discovery of petrol, in the nineteenth century, lead to increased interest in fossil energy sources. Inexpensive fossil fuels improved the quality of life and ushered in rapid industrialization. Geophysicist, M.K. Hubbert [1], was one of the first to point out problems facing increased demand for fossil fuel. In 1956, at a meeting of the American Petroleum Institute, he presented...

Agnieszka JAKUBIAK, Marzena RUTKOWSKA-FILIPCZAK – Institute for Fuels and Renewable Energy, Warsaw Please cited as: CHEMIK 2010, 64, 5, xx-xx The introduction of new regulations 2009/28/WE and 2009/30/WE forced the EU to take action to develop renewable energy sector. One of the requirements of Directive 2009/28/EC is to develop The Action Plans, these are national patterns of development of renewable energy. The need to develop this plans forced us to estimate the quantity of existing resources, renewable...

Jarosław FRYDRYCH, Krzysztof KOŁODZIEJCZYK – Institute for Fuels and Renewable Energy, Warsaw Please cited as: CHEMIK 2010, 64, 5, xx-xx The aim of this study was to estimate the impact of bio-components on the lubricating properties of diesel oil. Lubricating properties of methyl esters produced from selected plants and animal wastes were investigated. The relationship between structure and lubricity of tested bio-components were analyzed. Sets of diesel oil with tested bio-components blends were prepared for assessing their lubricating...
