Trabalho de Conclusão de Curso (Graduação em Química) - Instituto de Química, Universidade Federal do Rio Grande do Norte, Natal - RN, 2015.https://repositorio.ufrn.br/handle/123456789/38195Biodiesel can be made from vegetable oils, animal fats and fats reuse. Therefore, the demand for renewable raw materials, biodegradable has prompted several studies among these microalgae, since they have advantages when compared to higher plants. These have a high content of fatty acids by acreage may, in the future, by reducing the costs associated with its cultivation, ensuring the sustainability of the process. This work has to report comparative results Lipid particles with different sizes (0.3mm and 0,053mm), using the extraction solvent using mechanical agitation (hexane and hexane / isopropanol (3: 2.) And / or acid extraction. Featuring major constituents present in microalgae oil for biodiesel production, involving Monoraphidium sp species, whose fat content reaches 34,26% in its dry mass. Qualitative analysis of the extracted material was submitted regarding the composition, by Thin Layer Chromatography (TLC) spectroscopy, UV-Vis region, Infrared and Optical Microscopy. Quantitative analysis was performed by Thermogravimetric (TGA).openAccessMicroalgaBiodieselExtraçãoMicroalgae. extraction,Extraction.bachelorThesisQuímica
