The importance of R-(+)-limonene as the raw material for organic syntheses and for organic industry

Mariusz Władysław MALKO, Agnieszka WRÓBLEWSKA* – Institute of Organic Chemical Technology, West Pomeranian University of Technology, Szczecin, Poland Please cite as: CHEMIK 2016, 70, 4, 193–202 Limonene oxidation processes are one of the key methods for its management. Limonene extracted from the orange peels is a valuable raw material for the obtaining of valuable derivatives, for example: perillyl alcohol, which inhibits the growth the cancer of colon and breast. Limonene is a monoterpene compound which has many applications...

Overview of 4-oxopentanoic (levulinic) acid production methods – an intermediate in the biorefinery process

Andrzej FRANKIEWICZ* – Liquid Fuels and Bio-economy Department, Automotive Industry Institute, Warsaw, Poland Please cite as: CHEMIK 2016, 70, 4, 203–208 The civilization progress causes the increase in energy and propellants demand. Depleting natural sources such as coal, crude oil, natural gas, and changing world geopolitical situation caused, that the humanity started to turn to alternative energy sources. Biofuels (fuels resulting from the biomass processing) are a kind of these sources. The first generation biofuels consists of biofuels...
