40020-87-9 - Introduction
It is an organic compound that contains a benzofuran ring and acetyl and hydroxyl substituents in its chemical structure.
Its properties are as follows:
Appearance: yellow to orange-yellow crystalline powder substance;
Melting point: about 116-120 degrees Celsius;
Solubility: can be dissolved in ethanol, methanol and ether and other organic solvents.
It is mainly used in organic synthesis reactions, for example, it can be used to synthesize other organic compounds, and it can also be used as a raw material for dyes and fluorescent probes. In addition, it also has anti-inflammatory, antibacterial, antioxidant and other biological activities, so it also has certain applications in the field of medicine.
The preparation method can be achieved by the following steps:
1. p-hydroxybenzoic acid and ethyl acetate are heated to reflux under acidic conditions to generate ethyl 2-acetyl benzoate.
2. The 2-acetyl benzoic acid ethyl ester is reacted with ethanol and a small amount of sulfuric acid to generate calcium.
In the use of phenanthrene need to pay attention to its safety:
1. The substance may be irritating to the eyes, skin and respiratory system, and should be rinsed with plenty of water immediately after contact.
2. use to avoid dust, to prevent inhalation and throat.
3. storage should be closed storage, avoid contact with the oxidant.
4. During use, follow correct operating procedures and wear appropriate protective equipment, such as gloves, goggles and protective masks.
