Reaction Conditions

Reaction Steps

One hundred (100) parts by weight of a butadiene is dissolved into a solution of 153 parts of diethyl fumarate in 650 parts of benzene at 0° C. The reaction solution is then heated in a bomb at 50° C. for 24 hours. The solvent is removed by a distillation and the liquid crude product is purified by a fractional distillation under vacuum (b.p.: 102-105° C. at 2 mm);
