What is the melting point of p-chloroaniline?

P-chloroaniline appears as a white or pale yellow solid. Melting point 69.5°C.

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.

Is benzoic acid hazardous?

Benzoic acid is non-toxic and stable under ordinary conditions. While occupational exposure limits have not been established, benzoic acid may still pose a health risk and, therefore, the safe work practices should always be followed: Wash hands thoroughly after handling.

Is p-chloroaniline a base?

An acidic aqueous solution contains the salt* of p-chloroaniline, p-chloroanilinium hydrochloride*. You want to change p-chloroaniline hydrochloride (salt of an organic base*) to the water-insoluble p-chloroaniline (organic base) by converting the salt to a non-protonated* form.

Will 4-chloroaniline react with HCl?

The acid may then be recovered by evaporation of the combined ether extracts. This mixture may be readily separated by virtue of the fact that whereas 4-chloroaniline will react with HCl in water, benzoic acid will react with sodium bicarbonate (NaHCO3) in water, and 4-dibromobenzene is simply insoluble in water.

What is chloroaniline used for?

4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. 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.

Is 4-chloroaniline flammable?

FIRE HAZARDS * 4-Chloroaniline is a COMBUSTIBLE SOLID. * Use dry chemical, CO2, water spray, or an alcohol-resistant foam or other foaming agent.

What are the hazards of Naoh?

Contact with very high concentrations of sodium hydroxide can cause severe burns to the eyes, skin, digestive system or lungs, resulting in permanent damage or death. Prolonged or repeated skin contact may cause dermatitis. Repeated inhalation of sodium hydroxide vapor can lead to permanent lung damage.

What makes benzoic acid hazardous?

Hazard statements: Causes skin irritation Causes serious eye damage Causes damage to organs through prolonged or repeated exposure Precautionary statements: If medical advice is needed, have product container or label at hand Keep out of reach of children Read label before use Wear protective gloves/protective clothing …

What would happen if the sodium hydroxide extraction were done first?

Extraction with sodium hydroxide first would result only in bringing both acidic organic compounds into the aqueous layer – and no separation!

Is 4-chloroaniline an 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.

What does 4-chloroaniline smell like?

4-Chloroaniline is a white or pale yellow solid with a sweet odor.
