| Abstract: | The behavior of H_3PW_(12)O_(40) supported onto active carbon(HPW/C) is studied.The catalytic activity for the formation of ketal by using 2-butanone and ethyleneylycol is also studied.The results show that the yield of ketal is up to 67.3% by using the proposed catalyst,which is higher than that of using the unique H_3PW_(12)O_(40). |
