摘要：

Non-ionic triamino(imino)phosphoranes (phosphazenes) give excellent results as base catalysts for the water-free alcoholysis of vegetable fatty esters. Two phosphazene catalysts, with different intrinsic basicities, P-1-t-Bu and P-4-t-Bu, together with reaction parameters, such as temperature, alcohol/oil molar ratio, or catalyst concentration, have been studied. It was found that activity can be directly correlated to the basicity of the catalyst. Very high biodiesel yields (93-95% mol) were achieved under mild reaction conditions with methanol and ethanol. The catalyst can be recovered and recycled. (C) 2008 Elsevier B.V. All rights reserved.
