This is a continuation of a project started in 2018 by A. Tibbs.
Coumaryl alcohol is a monomer of lignin.
Coumaryl alcohol will be synthesized from coumaric acid through two separate reactions:
- First, coumaric acid will be converted into ethyl coumarate by through esterification. This will involve converting the carboxylic acid group into an ethyl ester group.
- Finally, ethyl coumarate will be converted into coumaryl alcohol through a reduction reaction.
The experiment performed is based off of a published paper in which the authors previously synthesized coumaryl alcohol. The "Synthesis of p-Coumaryl Alcohol" subheading is what's important.
- Initial procedure for the Synthesis of Coumaryl Alcohol (simplified):
- Add 1g p-Coumaric acid and 5mL acetyl chloride into a round bottom flask containing 50mL dry ethanol.
- Stir at room temperature for 17 hours
