Resumo: Macauba is an oleaginous palm tree widely found in Brazil. Its productive potential can reach 6000 kg of oil per hectare. In this study, crude vegetable oil was mechanically extracted from the mesocarp (pulp) of fresh Macauba fruit and subjected to physical-chemical determinations to analyse the following parameters: acid value, moisture content and kinematic viscosity. The results strongly indicate that Macauba palm oil is an alternative source of raw material for biodiesel production. Furthermore, concerning fatty acid composition, a predominance of unsaturated compounds was noted (75.92%) of which 63.21% are oleic acid, and 9.21% are linoleic acid. In this context, to produce ethyl esters, Macauba palm oil was subjected to alkaline transesterification by homogeneous catalysis, with microwave irradiation being applied to the heating step. The results indicated a conversion rate of 96.6%, for a molar ratio ethanol/oil of 12:1, a catalyst concentration equal to 1.0 wt% (KOH) and a reaction time equal to 60 seconds.

Neste trabalho, o óleo foi extraído da polpa fresca do coco de macaúba e algumas propriedades foram determinadas. Os valores do índice de acidez, teor de humidade e viscosidade cinemática indicam que este óleo é altamente recomendado como uma alternativa promissora para a produção de biodiesel. Além disso, a composição de ácidos graxos tem uma predominância de ácidos insaturados (75,9%), dos quais 63,2% e 9,2% são oleico e linoleico, respectivamente. Sequencialmente, este óleo foi submetido à produção de ésteres etílicos por transesterificação alcalina homogênea, por catálise básica e aplicando aquecimento por irradiação de microondas. Os resultados indicaram uma taxa de conversão de 96,61% para a razão molar de etanol/óleo de 12:1; concentração de catalisador de 1,0% (KOH) e tempo de reação de 60 s.Universidade Federal de Viçosa - UFV2016-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/kswpshttps://periodicos.ufv.br/jcec/article/view/244694160202301603410.18540/jcecvl2iss3pp034-046The Journal of Engineering and Exact Sciences; Vol. 2 No. 3 (2016); 034-046The Journal of Engineering and Exact Sciences; Vol. 2 Núm. 3 (2016); 034-046The Journal of Engineering and Exact Sciences; v. 2 n. 3 (2016); 034-0462527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941602023016034/pdfdo Nascimento Pereira, Marcos RobertoValério, Pedro PratesGrande, Salvador CarlosCaño de Andrade, Maria Helenainfo:eu-repo/semantics/openAccess2020-07-14T22:45:08Zoai:ojs.periodicos.ufv.br:article/2175Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2020-07-14T22:45:08Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
