4-Chloroaniline/Formula

Does 4-chloroaniline dissolve in water?

4-Chloroaniline (in the following called PCA) (CAS No. 106-47-8) is a colourless to slightly amber-coloured crystalline solid with a mild aromatic odour. The chemi- cal is soluble in water and in common organic solvents.

What is the Iupac name for 4-chloroaniline?

IUPAC Name 4-chloroaniline
Alternative Names 4-CHLOROANILINE p-Chloroaniline 4-Chlorobenzenamine
Molecular Formula C6H6ClN
Molar Mass 127.571 g/mol
InChI InChI=1S/C6H6ClN/c7-5-1-3-6(8)4-2-5/h1-4H,8H2

Is 4-chloroaniline a base?

In this experiment, you will separate a mixture of 4-chloroaniline (a weak base), benzoic acid (a weak acid) and 4-dibromobenzene (a neutral compound), which illustrates this general process. The benzoic acid then can be extracted as its sodium salt by extracting the ether layer with aqueous NaHCO3.

What is the melting point of 4-chloroaniline?

72.5 °C
4-Chloroaniline

Names
Melting point 72.5 °C (162.5 °F; 345.6 K)
Boiling point 232 °C (450 °F; 505 K)
Solubility in water 2.6 g/L at 20 °C
Hazards

How do you isolate 4-chloroaniline?

When the precipitation of the 4-chloroaniline is complete, it may be separated from the solution by filtering on a Buchner funnel (pg. 28, Fig. 1.9). The precipitate is then washed with a little cold water, dried on a sheet of filter paper and weighed.

Is 4-chloroaniline soluble in ether?

Separation of 4-Chloroaniline, Benzoic acid, and 4-Dibromobenzene. The separation here would be quite simple. Sodium chloride, an ionic salt, is soluble in water but insoluble in ether whereas cholesterol, a neutral organic molecule, is soluble in ether and only very sparingly soluble in water.

Is 4-chloroaniline a base or acid?

In this experiment, you will separate a mixture of 4-chloroaniline (a weak base), benzoic acid (a weak acid) and 4-dibromobenzene (a neutral compound), which illustrates this general process.

Is 4-chloroaniline an organic base?

In this exercise, you will begin with a mixture that contains an organic base, 4-chloroaniline, and a compound which is neither an acid nor a base, 1,4-dibromobenzene. Dibromobenzene will be recovered from the organic layer, while 4-chloroaniline will be recovered from the aqueous layer.

Is chloroaniline soluble in water?

p-Chloroaniline, a chlorinated aniline at 4 position, is a slightly yellow crystalline solid; melts at 70 C, boils at 232 C; soluble in hot water and readily soluble in most organic solvents. The vapour pressure and octanol/water partition coefficient are moderate.

Which is the correct formula for 4 chloroaniline?

4-Chloroaniline. 4-Chloroaniline is an organochlorine compound with the formula ClC 6 H 4 NH 2. This pale yellow solid is one of the three isomers of chloroaniline .

How is 4-Chloroaniline prepared from aniline?

This pale yellow solid is one of the three isomers of chloroaniline . 4-Chloroaniline is not prepared from aniline, which tends to overchlorinate. Instead, it is prepared by reduction of 4-nitrochlorobenzene, which in turn is prepared by nitration of chlorobenzene.

What is the melting point of p-chloroaniline?

P-CHLOROANILINE is a white or pale yellow solid. Melting point 69.5°C. 4-chloroaniline is a chloroaniline in which the chloro atom is para to the aniline amino group. It is a chloroaniline and a member of monochlorobenzenes.

What kind of drugs is 4-chloroaniline used for?

It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin, anilofos, monolinuron, and chlorphthalim. 4-Chloroaniline can be also used in the manufacture of some benzodiazepine drugs as well as the antihistamine dorastine, the antiarhythmic lorcainide,…
