| Abstract: | he ethylene glycol monoethyl ether acetate(I ) has been synthesized by using dynamic method. The reaction rates were determined bygas chromatographic analysis. A high activity and long service life zirconium-containing catalyst was chosen in comparison with several otherkinds of catalyst. The EtOCH2CH2OH conversion and selectivity for(I) were 97% and 100% respectively. The fresh catalyst and catalystsused for several times were studied by TPDE, XRD and TPD of pyridine. Because the crystal water of the catalyst produces strong sites ofBronsted acid, the catalyst possesses high activity.The crystal water ofthe catalyst is stable and its structure is not changed after use.Therefore, the catalyst containing zirconium has long service life. |
