Reaction Conditions:

with dihydrogen peroxide;nitric acid;cetyltrimethylammonim bromide;ferric nitrate in water at 80; for 5 h;Reagent/catalyst;Temperature;

Steps:

Will be 920g of glycerin,990gParaformaldehyde and20 g of the supported solid super acid catalyst prepared in Example 2 was addedIn the reaction device, the reaction is heated to 80 ° C, and the water having a lower boiling point and the trioxane formed in the reaction process enters the fractionation device.According to the principle that the boiling point of paraformaldehyde is lower than water, the triacetal is fractionated back to the reaction unit through a fractionation device.The reaction was carried out as a raw material, and the reaction was completed for 5 hours to obtain glycerol formal, and the product was analyzed by HPLC-MS.At 96.3%, the ratio of the six-membered ring product to the product of the five-membered ring in the product was 70:25.
