Polymer-Supported Azidoproazaphosphatrane: A Recyclable Catalyst for the Room…

A promising route for the quantitative transesterification of soybean oil (SBO) with methanol to biodiesel (FAMES) at room temperature is described using the Merrifield resin-supported catalyst resin-N3dP(MeNCH2- CH2)3N. This catalyst was recycled 11 times, although its activity decreased with time. Factors possibly responsible for catalyst deactivation are presented. Interestingly, the poly…
