Full textThe analytical methods currently used for chemical characterization of lignocellulosic materials were developed for wood and are applied with minor modifications for sugar cane bagasse and straw analysis. The lack of specific methodology for these materials leads to inadequate results and hamper both the planning and the interpretation of results. Thus, the main aim of this work is to develop specific analytical methodologies to the chemical characterization of sugar cane bagasse and straw. The determination of lignin was studied by the hydrolysis and dissolution of the polysaccharide fraction in sulfuric acid solution. The insoluble fraction was analyzed by elemental analysis, Fourier Transform Infrared (FT-IR), Carbon-13 nuclear magnetic resonance spectroscopy (13C NMR), Gel permeation chromatography (GPC) and Thermogravimetric analysis (TGA). The sugars and derivatives of these hydrolysates were analyzed by High performance liquid chromatography (HPLC). It was also performed a complementary analysis from the holocellulose content determinations in order to check the values obtained by the klason procedure. The results showed the dependence of sulfuric acid concentration on lignin content determinations and the role of condensation reactions in the lignin characteristics. Despite the similarities in chemical composition, klason lignins obtained from straw exhibited very low molar masses. Preliminary results obtained from holocellulose determinations showed also the need for optimized oxidation procedures in order to be successful applied to sugar cane bagasse analysis.

O Brasil é o maior produtor mundial de cana-de-açúcar, e com isso é também o maior gerador de biomassa residual – bagaço e palha. Uma grande parte dessa biomassa é utilizada na co-geração de energia, sendo queimada nas caldeiras das usinas, porém ainda há um enorme excedente, gerando problemas ambientais e sociais. Por isso, é necessário desenvolver projetos para utilização desse material, com valor agregado. Uma das maneiras é a utilização dos compostos que compõem a fibra do bagaço: celulose, hemicelulose e lignina. Para viabilizar a utilização desses compostos são necessárias técnicas pouco nocivas e com custo reduzido. Além disso, é importante que durante o processo de extração, haja pouca alteração estrutural dos compostos, ou que as alterações sofridas sejam benéficas para sua utilização posterior. O presente trabalho visou desenvolver métodos diferentes de extração de uma das frações dessa fibra, a lignina, avaliando as alterações sofridas durante os processos de extração para um posterior uso dessas ligninas de acordo com suas características. Os três métodos foram Organossolv utilizando uma mistura de dioxano e ácido clorídrico, Organossolv utilizando etanol e o Álcali. A caracterização das ligninas extraídas foi realizada através de técnicas de análise térmica (TG-DTG/DTA), microscopia eletrônica de varredura com aplicação de campo (MEV-FEG), espectroscopia de infravermelho (FTIR), e ressonância magnética nuclear (RMN). Através dos resultados obtidos nas análises evidenciou-se uma alteração maior na lignina extraída pelo método Álcali, com maiores rupturas nas ligações aromáticas durante o processo de extração quando comparado com as ligninas obtidas pelos dois métodos Organossolv. As três ligninas contêm estruturas carbônicas diferentes entre si, sendo que a que mais se aproxima da lignina de origem é a obtida pelo método Organossolv com dioxano.
Brazil is the huge producer of sugarcane worldwide, and it is also the largest residual biomass generator - bagasse and straw. A large part of this biomass is used for energy co-generation, being burnt in the boilers of the plants, but there is still a huge surplus, generating environmental and social problems. So it is necessary to develop projects to use this material with aggregate value. One way is the use of compounds that make up the fiber of bagasse: cellulose, hemicellulose and lignin. To enable the use of these compounds are required little harmful techniques and low cost. Moreover, it’s important that during the extraction process there is little structural change of the compounds or that suffered changes are beneficial for later use. This study aimed to develop different methods of extracting a fraction of this fiber, the lignin, evaluating the changes done by the extraction processes for later use these lignins according to their characteristics. The three methods were Organossolv using a mixture of dioxane and hydrochloric acid, Organossolv using ethanol and Alkali. The characterization of the extracted lignins was performed by thermal analysis techniques (TG-DTG / DTA), scanning electron microscopy with field application (SEM-FEG), infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR). The results obtained in the analysis revealed a greater change in the lignin extracted by the alkali method with larger breaks in aromatic bonds during the extraction process compared with the lignins obtained by the two methods Organossolv. The three lignins contain carbonic structures different from each other, and that is closest to the origin of lignin is obtained by Organossolv method with dioxane.

Full textThe present work aimed at the production of lignosulfonate, based in the lignin extracted from sugarcane bagasse-cane for using in phenolic resins. The extraction of lignin was carried out using the acetosolv process, which was optimised with a central composite design 22 to evaluate the effects of reaction time and temperature on the extraction yield, weight-average (M ̅w) and number-average (M ̅n) molecular weights, relative content of total hydroxyl, phenolic hydroxyl and methoxyl groups. The lignins obtained under conditions that maximized the extraction yield and showed better structural and thermal characteristics were sulfonated to obtain the lignosulfonates. The structural and thermal characteristics of the lignins and lignosulfonates were determined by FT-IR, GPC, 1H-NMR and 13C-NMR, DSC and TGA. The results show that the best extraction yield (64.5%) was obtained with 95% (w/w) of acetic acid, the addition of 0.1% HCl, at a temperature of 187 ÂC and reaction time of 40 min. However, with the same concentration of acetic acid and reaction time of 15 min at 187 ÂC, the extraction yield decreased to 55.6% Â 4.5%, without significant reduction. Furthermore, the increase in temperature of 187 ÂC to 205 ÂC was not enough to cause a significant increase in the relative content of hydroxyls and reduction of the relative content of methoxyl. These results show that the most appropriate conditions for adequate extraction of lignin for application in resins are: 95% (w/w) of acetic acid, addition of 0.1% of HCl, temperature of 187 ÂC and reaction time of 15 min. The acetosolv lignins showed p-hidroxifenila units as major constituent, higher thermal stability and higher purity than the commercial Kraft lignin. The glass transition temperature of the Kraft lignins was lower than that of the acetosolv lignin. This is due to the hydrophilic character and the presence of carbohydrates in the Kraft lignin. The lignosulfonates obtained in this study showed structural characteristics suitable for application in phenolic resins, because they showed high reactivity due to the greater presence of p-hidroxifenila units as major constituent, low molecular weights (40234878 g/mol), greater stability and greater purity compared to commercial sodium lignosulfonate. Therefore, lignosulfonates obtained in this work are more suitable for use in phenolic resins than commercial sodium lignosulfonate used for comparison.
O presente trabalho teve por objetivo a produÃÃo de lignossulfonato, a partir da lignina extraÃda do bagaÃo da cana-de-aÃÃcar para aplicaÃÃo em resinas fenÃlicas. Foi realizada a otimizaÃÃo da extraÃÃo da lignina do bagaÃo de cana-de-aÃÃcar utilizando o processo acetosolv. Para tanto, empregou-se um delineamento composto central 22 para analisar os efeitos do tempo de reaÃÃo e da temperatura no rendimento de extraÃÃo, massa molar ponderal mÃdia, massa molar numÃrica mÃdia, e conteÃdo relativo de hidroxilas totais, hidroxilas fenÃlicas e metoxilas. As ligninas obtidas nas condiÃÃes que maximizaram o rendimento de extraÃÃo e que mostraram melhores caracterÃsticas estruturais e tÃrmicas foram sulfonadas para obtenÃÃo dos lignossulfonatos. As caracterÃsticas estruturais e tÃrmicas das ligninas e dos lignossulfonatos foram determinadas por FT-IR, GPC, RMN-1H e 13C, TGA e DSC. Os resultados mostram que o melhor rendimento de extraÃÃo (64,5 % 4,2%) foi obtido com 95% (m/m) de Ãcido acÃtico, adiÃÃo de 0,1% de HCl, a uma temperatura de 187 C e tempo de reaÃÃo de 40 min. No entanto, com a mesma concentraÃÃo de soluÃÃo de Ãcido acÃtico e com tempo de reaÃÃo de 15 min a 187ÂC, o rendimento de extraÃÃo diminuiu para 55,6%  4,5%, nÃo sendo significativa esta reduÃÃo. AlÃm disto, a elevaÃÃo da temperatura de 187ÂC para 205ÂC nÃo foi suficiente para causar um aumento significativo no conteÃdo relativo de hidroxilas e reduÃÃo do conteÃdo relativo de metoxila. Esses resultados mostram que as condiÃÃes mais adequadas para extraÃÃo da lignina a ser aplicada em resinas sÃo: 95% (m/m) de Ãcido acÃtico, adiÃÃo de 0,1% de HCl, temperatura de 187 C e tempo de reaÃÃo de 15 min. As ligninas acetosolv apresentaram unidades p-hidroxifenila como constituinte majoritÃrio, maior estabilidade tÃrmica e maior pureza em relaÃÃo à lignina Kraft comercial. A temperatura de transiÃÃo vÃtrea da lignina Kraft foi menor do que à das ligninas acetosolv, devido à sua caracterÃstica hidrofÃlica e à presenÃa de carboidratos na lignina Kraft. Os lignossulfonatos obtidos no presente trabalho apresentaram caracterÃsticas estruturais adequadas para aplicaÃÃo em resinas fenÃlicas, pois mostraram alta reatividade devido a maior presenÃa de unidades p-hidroxifenila como constituinte majoritÃrio, baixas massas molares (4023 a 4878 g/mol), maior estabilidade e uma maior pureza em relaÃÃo ao lignossulfonato de sÃdio comercial. Portanto, os lignossulfonatos obtidos no presente trabalho sÃo mais adequados para aplicaÃÃo em resinas fenÃlicas do que o lignossulfonato de sÃdio comercial utilizado no presente trabalho.
