“…In isosorbide based EPs Chrysanthos et al [17] reached improved storage modulus below the T g , but the T g values were 50 C lower than the DGEBA based reference. In case of sucrose-based EPs prepared by Sachinvala et al [18] the break shear and Young's modulus values were similar to the values of DGEBA. The T g of epoxy-allyl-sucrose was below, while the T g of epoxy-crotil-sucrose was in the same range as the T g of DGEBA.…”

“…In order to enhance these properties, the next reasonable step is to mix bio-based epoxidized oils with petrol based EPs, mostly with DGEBA [9e14]. More promising results were achieved with epoxy monomers synthesized from polysaccharides, such as cardanol [15,16], isosorbide [17], sucrose [18] or rosin [19]. In the case of the cardanol based matrix [16], carboxyl-terminated polybutadiene liquid rubber was added to increase the tensile properties.…”

Recebido em 4/7/13; aceito em 10/10/13; publicado na web em 24/10/13 CARBOHYDRATES AS A SOURCE OF COMPOUNDS FOR FINE CHEMICAL INDUSTRY. Coal, oil, natural gas, and shale gas are biomass that is formed millions of years ago. These are non-renewable and depleting, even considering the recent discovery of new sources of oil in the presalt and new technologies for the exploitation of shale deposits. Currently, these raw materials are used as a source of energy production and are also important for the production of fine chemicals. Since these materials are finite and their (oil) price is increasing, it is clear that there will be a progressive increase in the chemical industry to use renewable raw materials as a source of energy, an inevitable necessity for humanity. The major challenge for the society in the twenty first century is to unite governments, universities, research centers, and corporations to jointly act in all areas of science with one goal of finding a solution to global problems, such as conversion of biomass into compounds for the fine chemical industry.Non-renewable raw materials are used in the preparation of fuels, chemical intermediates, and derivatives for the fine chemical industry. However, their stock in nature has a finite duration, and their price is high and will likely increase with their depletion. In this scenario, the alternative is to use renewable biomass as a replacement for petrochemicals in the production of fine chemicals. As the production of biomass-based carbohydrates is the most abundant in nature, it is judicious to develop technologies for the generation of chain products (fuels, chemical intermediates, and derivatives for the fine chemicals industry) using this raw material. This paper presents some aspects and opportunities in the area of carbohydrate chemistry toward the generation of compounds for the fine chemical industry.Keywords: fine chemicals; chains fine chemical from carbohydrates; renewable biomasses. INTRODUÇÃOA compreensão humana sobre a natureza e a vida é baseada em nosso conhecimento da química, pois, em realidade, todos os processos da vida são controlados por reações químicas.Há vários problemas globais 1,2 em que a química pode ser o elemento chave de sua solução e, desta forma, promover o avanço social e econômico dos países em um mundo sem fronteiras. A saber: 1. biodiversidade e conversão de biomassa em matérias-primas; 2. fontes alternativas de energia limpa e renovável; 3. produção sustentável de fármacos; 4. a produtividade agrícola para alimentar o crescimento populacional; 5. qualidade da água para uso humano; 6. materiais reclicáveis e pouco persistentes; 7. nível dióxido de carbono e seu aproveitamento; 8. risco de desaparecimento de alguns elementos químicos por dispersão; 9. nanotecnologia e nanotoxicologia; 10. educação em todos níveis e em especial em química e; 11. responsabilidade social da química.O grande desafio da sociedade no século XXI é unir governos, universidades, centros de pesquisa e corporações para que atuem conjuntamente e...

“…Sugar is a renewable resource that has the potential to replace mineral oil in the synthesis of EPs, furthermore due to its large oversupply in the recent decades its application as base material in polymer synthesis does not compete with the food industry. Sugar based EP components can be synthesized by replacing the hydroxyl groups of sugar structured molecules as cardanol [27][28][29], sucrose [30,31], maltitol, sorbitol [32] and isosorbide [33][34][35][36] with oxirane functions. With the mixture of a novel synthesized cardanol based novolac-type phenolic resins and polybutadiene liquid rubber (CTPB) tensile strength improvement and higher thermal stability could be achieved with increasing CTPB-content.…”

“…The EAS had lower and the ECS had higher tensile strength and modulus than the DGEBA. From sucrose based starting materials cured epoxidized sucrose ester of fatty acids can be formed, which has higher tensile strength and modulus than the commercially available epoxidized soybean oil (ESO) [31]. Shibata et al [32] achieved tensile strength improvement with 10 mass% microfibrillated cellulose fiber reinforcement in glycerol polyglycidyl ether (GPE) and sorbitol polyglycidyl ether (SPE) matrix materials.…”

Abstract. Curing and rheological behaviour, glass transition temperature, mechanical and thermal properties of two newly synthesized glucopyranoside-(GPTE) and glucofuranoside-(GFTE) based renewable epoxy resin (EP) components were investigated and compared to aromatic and aliphatic EPs. The glucose-based EPs can be successfully cured with amine and anhydride type curing agents, their gel times are suitable for processing and can be well-adopted to the needs of the common composite preparation methods. GPTE showed the highest glass transition temperature (T g ) among all investigated resins, followed by GFTE and DGEBA. Below the T g there was no significant difference between the storage modulus values of the EP systems. The glucose-based EPs had lower tensile and bending strength, but their tensile modulus values are not significantly different from the mineral oil based EPs. The thermal stability of the synthesized GPTE and GFTE is between DGEBA and the aliphatic resins. In applications where bending stresses are dominant over the tensile ones, and outstanding T g is required, these glucose-based resins offer a feasible renewable option.
