2. Melting Point: About -30 ℃
3. Boiling point: About 220 ℃
4. Refractive index: about 1.513
5. Solubility: Soluble in some organic solvents, such as ether and chloroform
Use:
Ethyl L has certain applications in organic synthesis, mainly for the synthesis of other compounds. It can also be used as a pharmaceutical intermediate for the synthesis of some drugs.
Method: The synthesis of
Ethyl L usually uses a four-member reaction, which reacts an appropriate amount of Ethyl acetate and pyrrole with methanol under the action of a strong acid catalyst (such as sulfuric acid) to obtain the target product. The synthesis process needs to pay attention to safety and avoid touching strong acids and harmful substances.
Safety Information:
1. Ethyl L is an organic compound and should be stored in a dry, well-ventilated place, away from fire and oxidizing agents.
2. During the operation should wear appropriate protective gloves, protective glasses and protective clothing. Avoid contact with skin and inhalation of gases or vapours.
3. If the compound is inhaled or ingested, seek medical advice immediately and bring the container or label for the compound.
4. This compound may be toxic to aquatic organisms, should avoid pollution to the environment. Observe local regulations when discarding.
