Heterogeneous catalysts (niobium phosphate, niobium oxide, gamma-alumina and zeolite HY) have been evaluated in interesterification reaction of macaw oil with methyl acetate, to produce fatty acid methyl esters (FAME) and triacetin. The reaction was conducted with a methyl acetate to oil molar ratio of 30:1, 5 wt% of catalyst and 250 degrees C. All the catalysts, except zeolite HY, exhibited good catalytic activity, and the most suitable were gamma-alumina and niobium phosphate, that reached a FAME and triacetin content of 51.60 wt% and 53.55%, respectively, in 2 h, which considering the maximum oil convertibility of 61.6 wt%, corresponds to 83.77 wt% and 86.93 wt% of conversion efficiency, respectively. The effect of reaction time was studied for these catalysts and it was observed that for gamma-alumina one hour of reaction was enough to reach 52.49 wt% of FAME and triacetin yield, corresponding to 85.21 wt% of conversion efficiency. On the other hand, in reaction with niobium phosphate two hours and a half were required to achieve 52.90 wt% of FAME and triacetin yield, corresponding to 85.87 wt% of conversion efficiency. gamma-alumina could be reused for at least 5 cycles without great activity loss, while niobium phosphate presented significant activity loss from the first to the second cycle.
