| titleOfInvention | Method for preparing bio-based polyol by tungsten-based solid acid catalyst catalyzed by oxidative hydrolysis of unsaturated oil |
| abstract | The invention discloses a method for preparing a bio-based polyol by catalyzing the oxidative hydrolysis of unsaturated fat with a tungsten-based solid acid catalyst. The tungsten-based solid acid catalyst, unsaturated fat, organic solvent and hydrogen peroxide are mixed, and the stirring reaction is carried out under the condition of a water bath. , after the reaction is completed, the tungsten-based solid acid catalyst is centrifuged to separate out the tungsten-based solid acid catalyst, and the reaction solution after removing the catalyst is subjected to rotary evaporation to recover the solvent and remove the water to obtain the target product bio-based polyol; wherein, the tungsten-based solid acid catalyst separated by centrifugation is used It is mixed with unsaturated oil, organic solvent and hydrogen peroxide, and the catalytic reaction is repeated; unsaturated oil is fatty acid containing unsaturated carbon-carbon double bond or fatty acid ester containing unsaturated carbon-carbon double bond. The catalyst used in the invention has good catalytic performance, clean process, simple and convenient operation, mild reaction conditions and short reaction time. |
