Organic sulfides in fuels have become one of the main sources of serious pollution. The desulfurization of fuels has become a frontier scientific topic demanding prompt solutions. Research shows that the emergence of ionic liquid analogues—deep eutectic solvents (DESs)—has provided a new opportunity for the deep extraction desulfurization of fuels because of their cheap and easily obtained raw materials, higher extraction desulfurization efficiencies, and simple and environmentally friendly synthesis process. In this study, some DESs were designed and synthesized. Choline chloride (ChCl), tetramethyl ammonium chloride (TMAC), and tetrabutyl ammonium chloride (TBAC) were chosen as typical hydrogen bond acceptors (HBA), and malonic acid (MA), glycerol (Gl), tetraethylene glycerol (TEG), ethylene glycol (EG), polyethylene glycol (PEG), and propionate (Pr) were chosen as hydrogen bond donors (HBD), from which a series of deep eutectic solvents were synthesized. Research shows that the above DESs can be used for the desulfurization of fuels successfully. Tetrabutyl ammonium chloride-based DESs possess the highest extraction efficiency. In optimal conditions, the extraction efficiency of TBAC/PEG can reach as high as 82.83% for one cycle, which is much higher than the traditional and functionalized ionic liquids (ILs). After five cycles, the extraction efficiency can reach up to 99.48%. In addition, sulfur content in fuels can be reduced to less than 8.5 ppm and deep desulfurization was realized. Finally, the extraction mechanism was investigated systematically with quantitative 1H NMR and FT-IR. The hydrogen bonds formed between DESs and benzothiophene (BT) account for the higher desulfurization efficiency. This study will provide new green solvents for the extraction desulfurization process of fuels.

Green Chemistry

Green Chemistry provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on, but not limited to, the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998). Green chemistry is the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry is at the frontiers of this continuously-evolving interdisciplinary science and publishes research that attempts to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. Submissions on all aspects of research relating to the endeavour are welcome. The journal publishes original and significant cutting-edge research that is likely to be of wide general appeal. To be published, work must present a significant advance in green chemistry. Papers must contain a comparison with existing methods and demonstrate advantages over those methods before publication can be considered. For more information please see this Editorial. Coverage includes the following, but is not limited to: Design (e.g. biomimicry, design for degradation/recycling/reduced toxicity…) Reagents & Feedstocks (e.g. renewables, CO2, solvents, auxiliary agents, waste utilization…) Synthesis (e.g. organic, inorganic, synthetic biology…) Catalysis (e.g. homogeneous, heterogeneous, enzyme, whole cell…) Process (e.g. process design, intensification, separations, recycling, efficiency…) Energy (e.g. renewable energy, fuels, photovoltaics, fuel cells, energy storage, energy carriers…) Applications (e.g. electronics, dyes, consumer products, coatings, pharmaceuticals, preservatives, building materials, chemicals for industry/agriculture/mining…) Impact (e.g. safety, metrics, LCA, sustainability, (eco)toxicology…) Green chemistry is, by definition, a continuously-evolving frontier. Therefore, the inclusion of a particular material or technology does not, of itself, guarantee that a paper is suitable for the journal. To be suitable, the novel advance should have the potential for reduced environmental impact relative to the state of the art. Green Chemistry does not normally deal with research associated with 'end-of-pipe' or remediation issues.
