| Abstract: | The method for preparing catalyst H_4SiW_(12)O_(40) was discussed.The catalytic activity of H_4SiW_(12)_(40) was validated in synthesizing cyclohexanone 1,2-propanediol ketal.In addition,the reaction conditions in synthesizing the other ketal(acetal) were discussed.The yields of the other products were 85.5% for cydohexanone 1,2-pnopanediol ketal,89.6% for cyclohexanone ethylene ketal,79.5% for butanone ethylene ketal,89.1% for N-butyraldehyde ethylene eacetal,and 81.5% for N-butyraldehyde 1,2-propanediol acetal,respectively. |
