Water → Dicyclopentadiene

Participants

Reaction Steps

The following example is for a case where an addition product of maleic acid to dicyclopentadiene produced from 1 mol (132 g) dicyclopentadiene, 1 mol (98 g) maleic anhydride and 1 mol (18 g) water is dehydrated and condensed with 0.6 mol (37.2 g) ethylene glycol. First, since the theoretic amount of the produced addition product of maleic acid to dicyclopentadiene is 1 mol, the weight is given by the equation: 132 g+98 g+18 g=248 g. Since there are 1.2 mol hydroxyl groups and 1 mol carboxyl groups, 1 mol water is eliminated with the condensation, and its weight is: 18×1=18 g. Therefore, the ratio of the dicyclopentenyl groups is given by the following equation: [133 g/(248 g+37.2 g-18 g)]×100=49.8 percent by weight.
