DIPHENYLAMINE Meaning and
Definition
-
Diphenylamine is a chemical compound that belongs to the class of organic compounds known as anilines. It is a crystalline solid with a white to pale pink coloration. The compound is composed of two phenyl groups attached to an amino group. Its molecular formula is C12H11N.
Diphenylamine has various applications in both industrial and laboratory settings. It is commonly used as a stabilizer in the production of explosives, particularly nitrocellulose-based ones, as it helps to prevent their degradation over time. Additionally, it is employed as an antioxidant in rubber and fuel products, as it can effectively inhibit the negative effects of oxidation.
In the laboratory, diphenylamine is utilized as a reagent for the detection and determination of the presence of nitrate ions. It acts as an indicator in chemical tests, exhibiting a blue color upon reaction with nitrates. This property makes it useful for analyzing water, soil, and plant samples to assess nitrate pollution or nitrate levels.
Furthermore, diphenylamine is used in the synthesis of several compounds, including dyes, pharmaceuticals, and agrochemicals. Its aromatic nature and amine functionality make it a versatile building block in the production of diverse organic compounds.
It is important to handle diphenylamine with care, as it may have harmful effects if it comes into contact with the skin, eyes, or is ingested. Appropriate safety precautions, such as the use of protective clothing and eyewear, should be taken when working with this compound.

Common Misspellings for DIPHENYLAMINE
Etymology of DIPHENYLAMINE
The word "diphenylamine" is derived from its chemical structure and the Greek roots of its components.
First, let's break it down:
1. "Di-" is a prefix indicating two.
2. "Phenyl" refers to a chemical compound called "phenyl group" or "benzene ring", which contains six carbon atoms arranged in a cyclic structure.
3. "Amine" is a term used in organic chemistry to denote a compound derived from ammonia, where one or more hydrogen atoms are replaced by organic groups.
Therefore, "diphenylamine" means a compound that consists of two phenyl groups attached to an amine structure.
The chemical itself was discovered and named in the mid-19th century.
