Benzene, 4-fluoro-1,2-dinitro- - Introduction
4-fluoro-1,2-dinitrobenzene, chemical formula C6H3F(NO2)2, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Colorless crystalline solid
-Melting point: 66-68 degrees Celsius
-Boiling point: 285 degrees Celsius
-relative molecular mass: 197.09
-Solubility: Slightly soluble in water, soluble in common organic solvents such as alcohols, ethers and ketones.
-Smell: chemical odor of benzene
Use:
- 4-fluoro-1,2-dinitrobenzene is mainly used as an intermediate in organic synthesis, used to prepare other organic compounds, such as pesticides and drugs.
-It can also be used as an acid indicator for acid-base titration reactions.
-In the dye industry, it can be used as a raw material for preparing dyes.
Preparation Method:
- 4-fluoro-1,2-dinitrobenzene can be prepared by nitration of fluorobenzene. First, fluorobenzene is mixed with nitric acid and heated to react to produce 3-nitrofluorobenzene. The 3-nitrofluorobenzene is then reacted again with nitric acid to give 4-fluoro-1,2-dinitrobenzene.
Safety Information:
- 4-fluoro-1,2-dinitrobenzene has high toxicity and is a hazardous chemical that must comply with relevant safety practices.
-Wear appropriate personal protective equipment such as chemical protective gloves, protective goggles and protective face masks when handling or touching.
-Avoid inhalation, ingestion or contact with skin. If contact occurs, rinse immediately with plenty of water and seek medical attention.
-During storage and use, keep away from heat sources, open flames and oxidants.
-Waste disposal shall comply with local environmental regulations, and other chemicals shall not be discharged or mixed at will. Hazardous waste shall be specially disposed.
Please note that when using and handling 4-fluoro-1,2-dinitrobenzene, correct laboratory operation and safety measures should be followed to ensure the safety of personnel and the environment.
