Green Aspects of Sample Preparation – a Need for Solvent Reduction
Growing public concern over protecting our environment obligates chemists, including analytical chemists, to change chemical activity in such a way that it will be conducted in an environmentally friendly manner. The article provides an overview of green chemistry issues relating to sample preparation techniques, concentrating especially on the green advantages of so-called solventless sample p...
متن کاملSelective reduction of condensed N-heterocycles using water as a solvent and a hydrogen source.
The reduction of unprotected indoles and quinolines is described using water as a hydrogen source. The method is based on the application of a RANEY® type Ni-Al alloy in an aqueous medium. During the reaction the Al content of the alloy, used as reductants, reacts with water in situ providing hydrogen and a RANEY® Ni catalyst, thus the alloy serves as a hydrogen generator as well as a hydrogena...
متن کاملA microvascular system for chemical reactions using surface waste heat.
Coffee-powered chemistry: Low-grade waste heat on surfaces can be used to drive chemical reactions, including the regeneration of a CO2 capture solution. Flowing two-phase heat transfer has been implemented within microvascular systems. This stripping system can be adapted to pre-fabricated surfaces, as demonstrated by a coffee mug containing a 1.2 m long microchannel. MEA=monoethanolamine.
متن کاملGreen procedure for synthesis of 3, 4 dihydropyrimidinones using 12-molybdophosphoric acid, as a catalyst and solvent free condition under microwave irradiation
Simple and improved conditions have been found to carry out the Biginelli reaction for the synthesis of 3, 4-dihydropyrimidin-2(1H) - one derivatives. This synthesis was performed in the presence of 12-molybdophosphoric acid (H3PMo12O40) as catalyst. These reactions were performed under solvent free conditions with microwave irradiation as the energy source. Compared with the classical Biginell...
متن کاملGuest in a Green Solvent
Soon, a decision will be made by the U.S. Secretary of Energy on whether to recommend Yucca Mountain in Nevada as the site for storage of highlevel radioactive waste. The waste would be stored in what is known as the saturated zone at Yucca Mountain. Here, water from rain and snow percolate downward to the water table, traveling along fractures in the rocks through the mountain and the reposito...
