Is nitroaniline soluble in water?


Density 1.437 g/ml, solid
Melting point 146 to 149 °C (295 to 300 °F; 419 to 422 K) (lit.)
Boiling point 332 °C (630 °F; 605 K)

Which is more polar ortho or para nitroaniline?

The proximity of amino and nitro functional groups in o-nitroaniline results in intramolecular hydrogen bonding, making the molecule less polar. These differences give o- and p-nitroaniline their unique uses, therefore it is very important to separate them.

Is 3 nitroaniline water soluble?


Melting point 114 °C (237 °F; 387 K)
Boiling point 306 °C (583 °F; 579 K)
Solubility in water 0.1 g/100 ml (20 °C)
Acidity (pKa) 2.47

Does nitrobenzene have a dipole moment?

Nitrobenzene has more dipole moment than nitro methane because in nitrobenzene there is greater charge separation due to the resonance. Therefore, it has less dipole moment.

Can hydrochloric acid explode?

William Andrew, Waltham, MA 2012. 1465. Hydrochloric acid and hydrogen chloride react violently with many metals, with the generation of highly flammable hydrogen gas, which may explode. Reaction with oxidizers such as permanganates, chlorates, chlorites, and hypochlorites may produce chlorine or bromine gas.

How common is 4-nitroaniline exposure in the US?

NIOSH (NOES Survey 1981-1983) has statistically estimated that 1448 workers (262 of these are female) are potentially exposed to 4-nitroaniline in the US(1). Occupational exposure to 4-nitroaniline may occur through dermal contact with this compound at workplaces where 4-nitroaniline is produced or used(SRC).

What is p nitroaniline used for?

p-Nitroaniline is an intermediate in the preparation of several azo dyes used for coloring consumer products. Toxicology and carcinogenicity studies were conducted by administering p-nitroaniline (>99% pure) in corn oil by gavage to groups of male and female B6C3F1 mice for 14 days, 13 weeks, and 2 years.

What does m-nitroaniline look like?

M-nitroaniline appears as yellow needles or yellow powder. (NTP, 1992) National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). 1992. National Toxicology Program Chemical Repository Database.

What is the difference between p-nitroaniline and 4 4 nitro aniline?

4-nitroaniline is a nitroaniline carrying a nitro group at position 4. It has a role as a bacterial xenobiotic metabolite. P-nitroaniline, [solid] is a yellow solid with a mild odor. Sinks in water. (USCG, 1999)
