Nature:
1. It is a white to light yellow crystalline solid with an aromatic aroma.
2. Stable at room temperature and soluble in organic solvents such as ethanol, ether, and chloroform.
3. Due to its phenolic group, it possesses certain chemical properties of phenols.
Usage:
1. Used in industries such as dye, pigment, and chemical manufacturing.
2. Used as an important raw material in organic synthesis, it can be used to prepare compounds such as dyes, fungicides, preservatives, etc.
Method:
The production of meconine is usually achieved by reacting naphthalene with molten sulfuric acid to form meconine sulfate, which is then hydrolyzed to obtain meconine. The specific synthesis process includes steps such as nitration, alkylation, hydrogenation, cyclization, etc.
Security:
1. Avoid contact with skin and eyes as they are irritating.
2. During storage and handling, attention should be paid to preventing contact with strong oxidants to prevent dangerous reactions.
3. Use Markonaine in a well ventilated environment to avoid inhaling its dust or vapor.
4. It is necessary to pay attention to following relevant safety operating procedures, and correctly use and dispose of the label.
