nitrogen trichloride
Học thuậtThân thiện
A chemist carefully handles a flask of nitrogen trichloride in the laboratory.
Definition
- Noun:
- A chemical compound with the formula NCl₃. It is a yellow, oily, and highly explosive liquid with a pungent, chlorine-like odor. Historically, it was used industrially under the trade name Agene as a bleaching and maturing agent for flour.
Usage Examples
- Noun:
- The laboratory synthesized a small, carefully controlled sample of nitrogen trichloride.
- Due to its instability, nitrogen trichloride must be handled with extreme caution.
- The use of nitrogen trichloride (Agene) in food processing was discontinued after health concerns were raised.
Advanced Usage
- Chemical Synthesis: Nitrogen trichloride is often discussed in the context of its formation as a hazardous byproduct in chemical reactions involving chlorine and ammonia, such as in swimming pool chlorination systems.
- Preventing the buildup of nitrogen trichloride is a critical safety measure in industrial chlorination processes.
- Historical Context: Its use is primarily referenced historically, particularly in relation to food science and industrial chemistry of the early 20th century.
- The banning of nitrogen trichloride as a flour treatment agent marked a significant change in food safety regulations.
Variants and Related Words
- Agene (n): The former trade name for nitrogen trichloride when used commercially as a flour bleach.
- NCl₃ (n): The chemical formula for nitrogen trichloride.
Synonyms
- Agene (specific to its commercial use)
- Trichloramine (a related chemical term often used in environmental chemistry, though not perfectly identical in all contexts)
Notes on Meaning
- The primary meaning of nitrogen trichloride is as a specific chemical compound. Its historical application under the name Agene is a secondary, context-dependent meaning relevant to food science and industrial history.
