RESUMO

Brazil, being the world?s greatest sugarcane producer and sugar exporter, represents a potential center for the production of sugarcane wax. This wax is obtained from the filter cakes, a sub-product of the sugar and alcohol industry. From the wax, it is possible to obtain concentrates of long chain fatty alcohols and fatty acids, compounds used in several applications related to human health. The objective of this work was to study different processes to obtain a concentrate of the fatty alcohols present in purified and clarified sugarcane wax, through saponification, acidulation and washing of the product with ethanol. A 68% purity fatty alcohol concentrate was produced by washing the saponified and acidulated wax, initially with hot water and then with cold ethanol. Through purification with acetone, the percentage of fatty alcohols reached 88%. The product currently available in the market presents a purity of 90% and, therefore, comparing the results obtained, it can be concluded that the fatty alcohol concentration process was efficient
