at 80 - 110; for 4 h;Large scale;Temperature;
Steps:
1-4 example 2
Maleic anhydride (490 g, 5 mol) was placed in a bubbling reactor, heated to 80 ° C to melt maleic anhydride, and continuously passed from the bottom of the bubbling reactor1,3-butadiene gas,The reaction temperature was controlled to 110 ° C. After 4 hours of reaction, the gas phase was detected, the reaction of the starting material was completed, and the temperature was solidified to obtain 746.3 g of a white solid. The yield was 98.1%.
