【 摘 要 】
The alternative system VO(acac)2/TBHPwas investigated for the epoxidation reaction of castor oil and its derivatives.Results of 88% of conversion, 73% of epoxidation and 82% of selectivity wereobtained for the system containing 20% excess of TBHP and 1% of VO(acac)2catalyst, during 3 h under toluene reflux. The product was characterized byGC/MS as methyl-cis-9, 10-epoxi, 12-hydroxystearate and quantitative1H NMR was used to calculate the data above. Preliminary resultsindicate that the heterogeneous system VO(acac)2 grafted on K10 claycan also promote epoxidation of castor oil.
