| Abstract: | Butanone 1, 2 -propanediol ketal was synthesized from butanone and 1,2 -propanediol using H4SiW12O40 as a catalyst. The optimal reaction conditions were screened by orthogonal test method. The yield of butanone 1,2 - propanediol ketal can reach 81.2% under the conditions that butanone is 200 mmol, molar ratio of butanone to 1,2 -propanediol glycol is 1 ： 1.4, the quantity of catalyst is equal to 0.5% of feed stocks, and the reaction time is 1.5 h ours. |
