RESUMO

Cashew-nut-shell-liquid (CNSL) is a phenolic oil that hás been due its their antioxirsion properties for use in fuels. The present work develops a method to the conversion of hidrogenated cardanol, that is the main component of the CNSL, in a compound with similar chacteristics to antioxidants used in products from petroleum. The antioxidants wasd obtained by exhaustive alkylation of the compound with tert-butyl chloride. After completing the optimization of several reaction steps, the product 2,4,6 tri-tert-butyl (pentadecylphenol) was obtained for the first tima. Characteeization and determination of physico-chemical properties were realized too, as well as wasd developed a study for check your application as an oxidative inhibitor by the molecular modeling. Estimation of process evalution was executed as well, where a rapid and practical computational methodology was utilizated in projects of the fine chemistry. The research showed satisfactory results and it could be concluded that the commercialization of this chemical products is feasible
