Benzene → 5-Norbornene-2-carboxylic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Benzene | HCID 241 | — |
| Reactant | Acrylic Acid | HCID 6581 | — |
| Reactant | Cyclopentadiene | HCID 7612 | — |
| Product | 5-Norbornene-2-carboxylic acid | HCID 78949 | 97.9% |
Reaction Steps
In 300 ml of benzene was dissolved 324.3 g of acrylic acid. Below 40° C., 327.2 g of cyclopentadiene was added dropwise to the solution over 2 hours. After agitation was continued for 12 hours at room temperature, the reaction mixture was concentrated in vacuum, yielding 608.5 g of 5-norbornene-2-carboxylic acid. The yield was 97.9%.
