Resumo: The alternative system VO(acac)2/TBHP was investigated for the epoxidation reaction of castor oil and its derivatives. Results of 88% of conversion, 73% of epoxidation and 82% of selectivity were obtained for the system containing 20% excess of TBHP and 1% of VO(acac)2 catalyst, during 3 h under toluene reflux. The product was characterized by GC/MS as methyl-cis-9, 10-epoxi, 12-hydroxystearate and quantitative ¹H NMR was used to calculate the data above. Preliminary results indicate that the heterogeneous system VO(acac)2 grafted on K10 clay can also promote epoxidation of castor oil.
