| titleOfInvention | A kind of method for condensation of polyol and ketone compound |
| abstract | The invention belongs to the technical field of synthesis of cyclic ketal compounds, and in particular relates to a method for condensing a polyhydric alcohol and a ketone compound. The method for condensing polyols and ketone compounds provided by the present invention is to first use an acidic catalyst to catalyze the dehydration condensation of polyols and ketone compounds, and then add a basic catalyst to react, and the reaction process of this method does not need to add other dehydrating agents and water-carrying agents. And other non-polar extraction solvents, it does not need to remove moisture, the operation is simple, the repeatability is good, and the conversion rate of polyols and ketones can be greatly improved after adding a basic catalyst, and the yield of products can be improved. |
