| Abstract: | Fructone has been synthesized from ethyl aceto-acetate and ethylene glycol with ferric solid-acid as the catalyst. The factors affecting the reaction have been studied. The optimal esterifying conditions were found out,the molar ratio was about one(ethyl acetoacetate)to 3. 0(eth-ylene glycol), the catalyst weight quantity was 6% (cat. / ethyl acetoacetate) and the reflux time was 2. 5h. The yield was up to 90. 8%. |
