| 摘要: |
Carbonated soybean oil (CSBO) is a precursor
of nonisocyanate polyurethanes (NIPUs). So far, the
ruling catalysts for CSBO synthesis through the coupling
of epoxidized soybean oil (ESBO) with CO2 are homogeneous
ones. In this work, a heterogeneous catalyst, 5 wt %
H3PW12O40 (PW)/ZrO2 was investigated for the coupling
reaction and proved quite efficient. However, the catalyst
showed poor reusability due to the difficult elimination of
bulky by–products retained in the spent catalyst. To remedy
this deficiency, the 5 wt % PW/ZrO2 was modified
with 0.3% Pt. It is found that Pt addition markedly
improved the reusability of the 5 wt % PW/ZrO2 without
loss in carbonation activity. An ESBO conversion of 78.3%
was obtained at the end of third recycle, indicating that Pt
species incorporated could promote the removal of the byproducts
and hence protect the active centres of 5 wt
%PW/ZrO2 catalyst. |
