Superacid Catalysis: Direct Esterification of Turpentine Oil with Acetic Acid. Chemical Engineering and Technology, v. 45, n. 5, p. 930-935, Mayo, 2022.1521-4125https://repositorio.fei.edu.br/handle/FEI/4473© 2022 Wiley-VCH GmbH.Terpenyl acetate, which is used for the production of flavors and fragrances, is industrially prepared from turpentine oil in a two-step process including hydration and catalytic esterification. Such processes have several shortcomings like too-large amounts of catalysts, non-recyclability of catalysts, long reaction times, and serious environmental pollution. Here, a direct one-step synthesis of terpenyl acetate from a feed mixture of turpentine oil and acetic acid with fluoroantimonic acid as superacid catalyst is described. Only 0.2 mol % of catalyst is necessary for up to 96 % conversion of starting material at room temperature. The desired product was obtained with a selectivity of up to 60 %. Thus, a clean and environmentally friendly strategy for synthesizing α-terpenyl acetate is provided.Acesso RestritoArtigo10.1002/ceat.202100416BiomassEsterificationPinenesSustainable chemistryTurpentine oil
