Green technology has become the primary concern of nations around the world. In-line with this concern, lignocellulosic biomass is often advocated as significant starting material for a greener production. However, the current biomass conversion cannot be considered as green due to the use of acid or alkaline during its pretreatment. An introduction of ionic liquids (ILs) as replacement of acids or alkaline for the pretreatment of lingo-cellulosic materials is gaining interest due to their minimal waste, nonvolatility and low toxicity and therefore considered green. This paper discusses the benefits of ILs as a green solvent for pretreatment of lignocellulosic biomass.

Lignin Model

Background: There is a developing demand for innovation in petroleum systems replacements. Towards this aim, lignocellulosic biomass suggested as a possible sustainable source for the manufacturing of fuels and produced chemicals. The aims of this paper are to investigate different kinds of β-O-4 lignin model compounds for the production of value-added chemicals in presence of ionic liquids. Especially, a cheap β-O-4 lignin model Guaiacol glycerol ether (GGE) (Guaifenesin) is introduced to produce valuable chemicals and novel products. Methods: Research related to chemical depolymerization of lignocellulosic biomass activity is reviewed, the notes from different methods such as thermal and microwave collected during at least 10 years. So, this collection provides a good source for academic research and it gives an efficient strategy for the manufacturing of novel value-added chemicals at an industrial scale. Results: This research presented that ionic liquid microwave-assisted is a power saving, cost efficient, fast reaction, and clean way with high selectively and purity for production of high value chemicals rather that conversional heating. Guaiacol and catechol are some of these valuable chemicals that is produced from β-O-4 lignin model compounds with high word demands that are capable to produce in industry scale. Conclusion: The β-O-4 lignin model compounds such as Guaiacol glycerol ether (GGE) (Guaifenesin) are good platform for developing food materials, perfumery, biorefinery, and pharmaceutical industry by ionic liquids-assisted lignin depolymerization method.

AbstractBoosted by the simplicity of their synthesis and low toxicity, cholinium and amino acid-based ionic liquids have attracted the attention of researchers in many different fields ranging from computational chemistry to electrochemistry and medicine. Among the uncountable IL variations, these substances occupy a space on their own due to their exceptional biocompatibility that stems from being entirely made by metabolic molecular components. These substances have undergone a rather intensive research activity because of the possibility of using them as greener replacements for traditional ionic liquids. We present here a short review in the attempt to provide a compendium of the state-of-the-art scientific research about this special class of ionic liquids based on the combination of amino acid anions and cholinium cations.

Good And Evil

Although Nietzsche's greatness is recognized more universally now than ever before, the nature of that greatness is still widely misunderstood, and that unfortunately means that before I discuss any of Beyond Good and Evil (henceforth BGE) in any detail, I must make some general remarks about his work, his development and the kind of way in which I think that it is best to read him. Unlike any of the other philosophers that this series includes, except Marx and Engels, Nietzsche is very much concerned to address his contemporaries, because he was aware of a specific historical predicament, one which he would only see as having worsened in ways which he predicted with astonishing precision in the century since he wrote his great series of works. For he was above all a philosopher of culture, which is to say that his primary concern was always with the forces that determine the nature of a particular civilization, and with the possibilities of achievement which that civilization consequently had open to it. One of the reasons that The Birth of Tragedy, his first book, published when he was twenty-eight, created such a surge of hostility in the world of classical scholarship was that in it, whilst undertaking an investigation of what made possible the achievements of fifth century BC Greece in tragic drama, he felt it necessary to elicit the whole set of fundamental beliefs which the Greeks shared, and also to draw metaphysical conclusions from the fact that they were able to experience life in such a way that they needed great tragedies in order to endure it.
