Reaction Conditions:
with aluminum oxide;caesium carbonate in diethyl ether at -5 - 10;Large scale;Reagent/catalyst;Temperature;
Steps:
6 Example 6
Filled with heterogeneous solid heteropolyacid supported catalyst cesium carbonate,30 kg of acetaldehyde was put into the fixed bed reactor with γ-Al 2 O 3 ,1.5kg of ether, cooled to -5 ° C, began the reaction, the temperature during the reaction was controlled at 10 ° C,After the reaction is completed, the mixture is filtered, and the solid is washed with water and dried to obtain tetraacetaldehyde, and the content is 99.3%.The yield was 15.1%. The filtrate is distilled, sulfuric acid is added as a catalyst, the paraldehyde in the filtrate is depolymerized, and acetaldehyde and diethyl ether are separated by distillation, and the next time the feed is taken.
