摘要

A novel class of fiber supported ionic liquids (FSILs) was first used to catalyze fructose dehydration to 5-hydroxymethylfurfural (HMF) and exhibited excellent catalytic activity in terms of 86.2% and 84.7% HMF yield at 100 °C for 30 min in DMSO and 45 min in a mixed-aqueous system respectively, as well as the ability to be very easily recycled, with superior catalytic activity and stability even after 10 cycles. The procedures can be scaled up and the formed HMF can be easily obtained by simple distillation, and the solvent can be recycled. The fiber catalytic process is much better than that via acid resins and silica supported ionic liquid nanoparticles in yields and recyclability, and its extremely simple separation operation and low catalyst dosage as well as selectivity are significantly superior to the single ionic liquid catalysis and liquid–liquid biphasic system of ionic liquid catalysis. This is the first report on the application of the inexpensive and readily available polypropylene fiber (PPF) as a new support for ionic liquids, and the prominent features of PPF and the remarkable performance of FSILs are very attractive to the chemical industry.

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.
