| Abstract: | The behavior of H3PW12O40 supported onto active carbon(HPW/C)was studied.The catalytic activity for the formation of ketal by using isobutyl aldehyde and ethylene glycol was also studied.The results showed that the yield of ketal was up to 73.4%using the proposed catalyst,which was higher than that of using the unique HPW. |
