Popis: |
The ability of bis(acetyl-acetonato)dioxo-molybdenum (VI) [MoO 2 (acac) 2 ] to catalyse the epoxidation of soybean oil in the presence of tert -butyl hydroperoxide as oxidizing agent has been investigated. The influence of reaction time and temperature in the course of the epoxidation reaction was evaluated by quantitative 1 H NMR. When epoxidation was carried out in refluxing toluene at 110 °C for 2 h, a 70.1% conversion of substrate was obtained, producing 54.1% epoxidation with a selectivity of 77.2%. The 1 H NMR spectroscopic method selected for the purpose of this work allowed a simple and rapid evaluation of the mono- and diepoxides obtained following the epoxidation of soybean oil. |
