Sustainability was poorly defined originally, since the key requisite to accurately forecast the needs of future generations remains difficult to pinpoint. Consequently, sustainability was replaced with suitability by many stake holders, as they had vested and/or conflicts of interests to label suitable developments sustainable. The sustainable development goals recently introduced by the United Nations seem to serve as a ‘roadmap to happiness’ instead of metrics. A simple and independent definition of sustainability was recently provided: Nature's resources, including energy, should be used at a rate at which they can be replaced naturally, and the generation of wastes cannot be faster than the rate of their remediation by Nature. The ethanol equivalent, the sustainability values of resource replacement and fate of waste, and the sustainability indicator have been recently defined to measure the sustainability of biomass-based carbon-chemicals and renewable energy. The production of ethylene, propylene, toluene, xylenes, styrene, and ethylene oxides cannot be sustainable due to the limited amount of bioethanol. The required volume of corn and the corresponding size of land are only enough to replace one sixth of fossil resources in the USA, EU, and China, and practically insufficient in Canada and the Russian Federation. Until the utilization of electricity becomes practical and economical in aviation, biomass-based liquid fuels are the sustainable alternative.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116561846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, considerable steps forward have been made with the aim of developing greener routes for the functionalisation of phenol and diphenols. Examples of these include: (a) the use of methanol instead of methylchloride or dimethylsulphate for the synthesis of ethers, such as anisole, guaiacol and veratrol, which are key intermediates for the synthesis of a plethora of fine chemicals and specialties; (b) the use of alkylcarbonates for the synthesis of alcohol-ethers (e.g. phenoxyethanol), cresols, and ethers; and (c) the use of aldehydes instead of halogenated alkanes for the hydroxyalkylation of phenolics to alcohols, such as piperonyl alcohol. Indeed, many of these reactions were inspired by the successful industrial application of methanol as an electrophile for the synthesis of o-cresol and 2,6-xylenol. The latter reaction may be considered the very first ‘green’ process for the functionalisation of phenol; surprisingly, despite its industrial use for several decades, only in recent years has the mechanism of this reaction been elucidated. Some emblematic examples of the more sustainable synthesis of phenolic compounds, briefly discussed here, are 2,6-xylenol, guaiacol, vanillin, methylendioxobenzene, phenoxyethanol, hydroxytyrosol and piperonal.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133688431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present EU's biofuel policy introduces a blending target involving reaching a mandatory 6% reduction in the greenhouse gas intensity of fuels by 2020. Thus, biodiesel production that is sustainable in terms of feedstock, as well as of employment of clean, safe, and efficient manufacturing processes, is becoming urgent. In the past decade, many industrial processes have shifted toward the use of solid acid catalysts as a ‘green tool’ to replace traditional catalytic systems to efficiently produce biodiesel from low-cost biomass feedstock, i.e., resources with high free fatty acid content. Heterogeneous systems, indeed, enable their easy separation and recovery, recycling and reuse, possibly leading to waste-minimized protocols. Moreover, there is an ever-growing interest in exploiting the synergy between heterogeneous catalysis and continuous flow technology as a viable integrated sustainable solution to process intensification. In this chapter, we focus on the recent advances in the use of tuneable and versatile organic polymer-supported solid acid catalysts to produce biodiesel fuel in batch and in continuous mode. We restrict the discussion to the most widely employed members of this class, i.e., cation-exchange resins. Trends are identified between physico-chemical and morphological properties of the catalysts and their performance, while their recyclability aspects are also examined. Finally, a survey and brief discussion on these catalysts' performance in batch and continuous flow production of levulinates – biofuel additives structurally related to biodiesel – are also provided.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
