Document Summary
Salicylic acid is an organic carboxylic acid which is derived from the metabolism of salicin which is produced in willow bark. Although salicylic acid displays its own pain relieving properties, its acidity is too high and can cause severe stomach pain when ingested. Esterification of salicylic acid with acetic anhydride yields acetyl salicylic acid (aspirin) Morphine, heroin and codeine are all examples of drugs from the opiate family. n a series of transformations, morphine is esterified with acetic acid to yield heroin. Codeine is another opiate in which the ester is replaced by an ether. -opiates, originally derived from the poppy plant, have been around for thousands of years. People use opiates for both recreational and medicinal purposes. Some opiates come from the raw, natural opium. While other opiates are manufactured to have the same chemical structure as the raw opium.
