Abstract: Copaiba oil-resin has aromatic characteristics and pharmacological activities attributed to sesquiterpenes compounds. These purified compounds present application in perfume, pharmaceutical and cosmetic industries. Therefore, the objective of this work was to use molecular distillation to recover and purify sesquiterpenes of the copaiba oil-resin with purity high. The parameters evaporator temperature (TEV) from 45 to 100 degrees C and feed flow rate (Q) between 15 and 30 ml min(-1) were evaluated through design of experiments (22 with center points). The results showed that it was possible to recover sesquiterpenes with 98.12% purity in the distillate stream. Increased in TEV and reduction in Q were the effects observed experimentally and through the response surface. The best experimental condition was TEV of 100 degrees C and Q of 15 mL min(-1). Collor differences were noticed between distillate streams (colorless) and residue (brown). These can be used as parameters for separation of sesquiterpenes and diterpenes. The molecular distillation proved to be an efficient processo to both recovery and purification of sesquiterpenes from the copaiba oil-resin.
