for HPLC was used as reaction medium (J.T.Baker,99.99%)
and H2O2 30% w/w (Merck) was used for decomposition tests,
while analyses used potassium iodide (Sigma-Aldrich),Hydra-
nal-Composite 2 (Fluka),dry methanol for KFT (Fluka),acetic
acid (Sigma-Aldrich),sodium thiosulfate penta-hydrate (99.5%,
Sigma-Aldrich),starch (Sigma-Aldrich),and potassium dichro-
mate (Riedel de Haen).Catalyst has been prepared as already¨
14reported and pre-reduced in situ before use.Preliminary tests
of H2O2 decomposition were carried out to ascertain that the
support alone does not decompose H2O2.We used pure calcined
sulfated ceria at 20 °C,1 bar for 5 h.14
Reactor Setup for the Experiments.A cocurrent,downflow
TBR was developed.In addition to the motivations already
mentioned,the TBR allows short liquid residence time if
required for selectivity.It is a steady-state reactor,so that
chemical analysis has no limitation on the sampled
答案
高效液相色谱法作为反应介质(最难贝克,99.99%) 和过氧化氢30% w / w(默克公司)是用于分解测试, 在分析使用碘化钾(Sigma-Aldrich),九头蛇- nal-Composite 2(丙烯酰胺)、干燥KFT(丙烯酰胺)甲醇...
