The increase in atmospheric carbon dioxide is linked to climate changes; hence there is an urgent need to reduce the accumulation of CO2 in the atmosphere. The utilization of CO2 as a raw material in the synthesis of chemicals and liquid energy carriers offers a way to mitigate the increasing CO2 buildup. This review covers six important CO2 transformations namely: chemical transformations, photochemical reductions, chemical and electrochemical reductions, biological conversions, reforming and inorganic transformations. Furthermore, the vast research area of carbon capture and storage is reviewed briefly. This review is intended as an introduction to CO2, its synthetic reactions and their possible role in future CO2 mitigation schemes that has to match the scale of man-made CO2 in the atmosphere, which rapidly approaches 1 teraton.

Sustainable routes to polyurethane precursors

A method for producing Cu films with low resistivity, based on low temperature sintering, is demonstrated. The Cu inks for preparing conductive Cu films consisted of Cu particles that were coated with a decomposable polymer (poly(propylenecarbonate), PPC) as well as a self-reducible copper formate/1-amino-2-propanol (CuF–IPA) complex as an additive. The sintering temperature used in this study was as low as 100 °C. Following sintering at a temperature of 100 °C, the lowest reported resistivity (8.8 × 10−7 Ω m) was achieved through the use of Cu-based metal–organic decomposition (MOD) inks. This was due to the dual promotional effects of the aminolysis of PPC with IPA and the pyrolysis of the CuF–IPA complex.

A supercritical carbon dioxide extraction from mixtures of triglycerides and higher fatty acid methyl esters using a gas-effusion-type system

The extraction of some organic substances from freezed-dried mackerel powder was performed using supercritical carbon dioxide (SC–CO2) at 4.9–24.5 MPa and 313 K in a fixed-bed flow extractor. It was found that the rate of extraction was enhanced by raising the pressure. The overall yield of the SC–CO2 extraction was comparable to that of a hot-hexane-extraction from the same material. The SC–CO2 extraction produced glycerides of pharmacologic significance such as icosapentaenoic acid (IPA) and docosahexaenoic acid (DHA) from mackerel. In addition, a kinetic model for extraction with supercritical fluids is described, and is applied to correlate our results obtained in the SC–CO2 extraction of mackerel. This model could express the transport within the solid in the supercritical fluid extraction process.

Reactions of 2-methoxy-3,3-dimethyl-2-phenyloxirane or α-bromoisobutyrophenone and carbon dioxide in the presence of aliphatic α,ω-diamines were investigated. 1,4-Butanediamine, 1,6-hexanediamine, 1,8-octanediamine, and 1,4-bis(aminomethyl)benzene afforded corresponding 3-(ω-aminoalkyl)-4-hydroxy-5,5-dimethyl-4-phenyl-2-oxazolidinones and 3,3′-polymethylenebis[4-hydroxy-5,5-dimethyl-4-phenyl-2-oxazolidinones] derivatives, while ethylenediamine gave only mono(2-oxazolidinone) derivative.
