4-OXO-1,2,3,4-TETRAHYDROCARBAZOLE - Introduction
1,2,3, (tetrahydrofurfuryl ketone), chemical formula C5H10O2, is a colorless liquid. Its main properties are as follows:
1. Solubility: 1,2,3, soluble in many organic solvents, such as ethanol, ether and Ketone solvents.
2. Melting point and boiling point: 1,2,3. The melting point is -45 ℃ and the boiling point is 174 ℃.
3. Stability: 1,2,3, stable, not easy to decompose, and can be stored for a long time.
1,2,3, the main uses are:
1. Industrial use: as an organic solvent, used in paints, coatings, adhesives, plastics and other industries.
2. Medical use: as a chemical intermediate, can be used in drug synthesis, pharmaceutical preparations and other fields.
The method for preparing 1,2,3, 5 is generally hydrogenated tetrahydrocarbazole. The specific preparation method is as follows:
Tetrahydrocarbazole is dissolved in an alcohol or ester solvent, and hydrogen is used as a reducing agent, and a hydrogenation reaction is carried out under the condition of adding an appropriate amount of catalyst (such as palladium or platinum). The reaction is usually carried out under normal pressure or reduced pressure, and the reaction temperature is between room temperature and 80°C.
Safety Information:
1,2,3, relatively safer, but still need to pay attention to the following matters:
1. Avoid contact with strong oxidants to prevent fire or explosion.
2. In the use of the process should pay attention to avoid contact with skin and eyes, such as accidental contact, should immediately rinse with water.
3. In the process of operation, should maintain a good ventilation environment, avoid inhalation of steam.
4. Storage should be away from fire and heat sources, and keep the container closed, avoid direct sunlight.
Note: The above content is for reference only. The specific use and safe operation need to be evaluated and implemented according to the specific situation.
