Abstract

In this work, we produced phenol directly from benzene using silicates modified with Al and Fe. The preparation of Al and Fe-silicates was done at 373 K by mixing a silicate solution with Al and Fe sources and the resulting material were dried at 373 K overnight and calcined at 823 K. The calcined materials were characterized using XRD, IR, SEEM and SBET. The oxidative properties of resulting solids (Al and Fe-silicates) were tested in the catalytic oxidation of benzene to phenol at different temperatures. The oxidation processes were followed up using HPLC and UV-Vis Spectrophotometry.

催化苯制苯酚的阳离子改性硅酸盐

在这项工作中，我们用铝和铁改性的硅酸盐直接从苯中生产苯酚。在373 K的温度下，将硅酸溶液与Al和Fe源混合，制备出Al和Fe硅酸盐，并在373 K下干燥过夜，在823 K下煅烧。采用XRD、IR、sem和SBET对煅烧后的材料进行了表征。在不同温度下，对苯催化氧化制苯酚过程中生成的固体(Al和fe -硅酸盐)的氧化性能进行了测试。采用高效液相色谱法和紫外-可见分光光度法对氧化过程进行跟踪。

期刊介绍： Publication of the journal started in 1974. Its original name was “KKU Engineering Journal”. English and Thai manuscripts were accepted. The journal was originally aimed at publishing research that was conducted and implemented in the northeast of Thailand. It is regarded a national journal and has been indexed in the Thai-journal Citation Index (TCI) database since 2004. The journal now accepts only English language manuscripts and became open-access in 2015 to attract more international readers. It was renamed Engineering and Applied Science Research in 2017. The editorial team agreed to publish more international papers, therefore, the new journal title is more appropriate. The journal focuses on research in the field of engineering that not only presents highly original ideas and advanced technology, but also are practical applications of appropriate technology.
