Title: Ethenolysis of esters of vegetable oils: Effect of B2O3 addition to Re2O7/SiO2.Al2O3-SnBu(4) and CH3ReO3/SiO2.Al2O3 metathesis catalysts

Abstract: Impregnation of SiO2.Al2O3 (24.3% Al2O3) with 6% B2O3 increases the activity of supported Re2O7 in the ethenolysis of methyl oleate, but reduces the activity of CH3 ReO3 on the same support. Re2O7/SiO2.Al2O3/B2O3-SnBu(4) is shown to be an effective catalyst for the ethenolysis of methyl linoleate and of the methyl esters of olive oil, and can be recycled after calcination at least five times without loss of activity.
