Preparation of Iron system New pattern Solid Superacid Fe_2O_3/S_2O_8~(2-)/La~(3+) And Studied on Synthesis of Cyclohexanone Glycol Ketal

Using self-command iron system new pattern solid superacid Fe2O3/S2O82-/La3+as catalyst. Cyclohexanone and glycol as material, the synthesis of cyclohexanone glycol ketal was studied.The influence factors such as amount of catalyst,ratio of cyclohexanone and glycol,and the reaction time were also studied. The results showed that:molar ratio of cyclohexanone to glycol was 1:1.2 , mass of catalyst was 0.5 g , the volume of cyclohexane was 15ml, reaction time was 1.5h. Under the optimum conditions,collect 174-178℃ cut fraction, the yield of condensation was up to 91.8%.
