2-hydroxy-9H-fluoren-9-one - Introduction
2-Hydroxy-9-fluorenone is an organic compound with the chemical formula C13H8O2. The following is a description of the properties, uses, preparation and safety information of 2-Hydroxy-9-fluorenone:
Nature:
2-Hydroxy-9-fluorenone is a white or yellow crystalline solid with an aromatic flavor. It has a high melting point and boiling point, can be dissolved in some organic solvents such as ethanol, ether and methylene chloride, and almost insoluble in water. It can undergo photochemical reactions under light to generate aromatic compounds.
Use:
2-Hydroxy-9-fluorenone has a wide range of applications in the fields of fluorescent dyes, organic optoelectronic devices and antioxidants. It can be used as an intermediate in organic synthesis for the synthesis of other organic compounds. In addition, it can also be used as a raw material for dyes, fluorescent agents and cosmetic materials.
Preparation Method:
The preparation of 2-Hydroxy-9-fluorenone is usually obtained by reacting fluorenone with hydrogen peroxide under strong alkaline conditions. The specific step is reacting fluorenone with hydrogen peroxide under alkaline conditions to generate 2-Hydroxy-9-fluorenone. The reaction conditions can be adjusted according to the specific experimental conditions.
Safety Information:
2-Hydroxy-9-fluorenone is generally considered to be a relatively safe compound, but appropriate protective measures are still required. In case of contact with skin and eyes, rinse immediately with plenty of water. During the operation, avoid inhaling its vapor, so it is necessary to operate in a well-ventilated place. In addition, when storing and handling 2-Hydroxy-9-fluorenone, avoid contact with oxidants to prevent fire or explosion. Personal protective equipment, such as laboratory gloves and eye protection, is recommended to reduce risk.
