- Keep container tightly closed in a dry and well-ventilated place. …
- Store in cool, dry, well-ventilated location away from fire hazards and reactive materials. …
- Separated from strong oxidants, strong acids and food and feedstuffs. …
- Aniline is slightly corrosive to some types of metal.
How do you handle an aniline spill?
Quickly remove contaminated clothing
. Wash contaminated skin with large amounts of soap and water. Seek medical attention immediately. Begin artificial respiration if breathing has stopped and CPR if necessary.
Can aniline be safely handled?
prohibited where Aniline
is used, handled, or stored in a manner that could create a potential fire or explosion hazard.
What are the hazards of aniline?
Aniline is
irritating to the skin, eyes, and respiratory tract
. Effects can result from all routes of exposure. Aniline induces methemoglobinemia, which impairs the delivery of oxygen to tissues. Aniline may also cause the destruction of red blood cells, which manifests as acute or delayed hemolytic anemia.
Does aniline dissolve in water?
Moderately soluble in water
. Aniline is miscible with alcohol, benzene, chloroform, carbon tetrachloride, acetone, and most organic solvents.
Is aniline explosive?
| Names | Flash point 70 °C (158 °F; 343 K) | Autoignition temperature 770 °C (1,420 °F; 1,040 K) | Explosive limits 1.3–11% | Lethal dose or concentration (LD, LC): |

Is aniline a hazardous substance?
The International Agency for Research on Cancer (IARC) determined that aniline is not classifiable as to its carcinogenicity to humans. The EPA has determined that
aniline is a probable human carcinogen
.
What are the uses of aniline in our daily lives?
Aniline is used in
rubber accelerators and anti-oxidants, dyes and intermediates, photographic chemicals
, as isocyanates for urethane foams, in pharmaceuticals, explosives, petroleum refining; and in production of diphenylamine, phenolics, herbicides and fungicides.
Is aniline solid or liquid?
Aniline is a
colourless to brown, oily liquid
which darkens on exposure to air and light. It has a characteristic amine odour (detectable at 0.6 to 10 ppm ) and burning taste. Hygroscopic. Moderately soluble in water.
Why aniline does not dissolve in water?
Aniline does
not undergo hydrogen bonding due to the presence of benzene
which is hydrophobic. … Due to these effects dissolving aniline in water isn’t possible, and so aniline is insoluble in water.
Why is aniline considered a weak base?
Aniline only reluctantly accepts a proton to form the anilinium ion
, and hence is a weak base. … It is less reluctant to accept a proton on its nitrogen lone pair, and hence aliphatic amines are stronger bases.
What happens when aniline reacts with nitrous acid?
In acidic solution, nitrous acid
converts aniline into a diazonium salt
that is an intermediate in the preparation of a great number of dyes and other organic compounds of commercial interest. When aniline is heated with organic acids, it gives amides, called anilides, such as acetanilide from aniline and acetic acid.
Is aniline or cyclohexylamine a stronger base?
In cyclohexylamine, the cyclohexyl group (non-aromatic) is an electron releasing group and thus increases electron density on the nitrogen of – NH
2
group and makes it a
stronger base than aniline
(Inductive effect
What happens when aniline is heated?
When aniline is heated with organic acids,
it gives amides, called anilides, such as acetanilide from aniline and acetic acid
. … Catalytic reduction of aniline yields cyclohexylamine. Various oxidizing agents convert aniline to quinone, azobenzene, nitrosobenzene, p-aminophenol, and the phenazine dye aniline black.
Why aniline is basic in nature?
Aniline is an aromatic compound in which an amino group is attached to the benzene ring. … The basic nature of aniline is due to
the presence of amino group N H 2 {rm{N}}{{rm{H}}_{
rm{2}}} NH2, which has one lone pair of electrons on the nitrogen atom. Aniline, on reaction with a stronger acid, forms anilinism ion.
