2-Chloroaniline Usage And Synthesis

Chemical Properties	clear pale yellow to brown liquid

General Description	Clear amber liquid with an amine odor. Occurs in both alpha and beta forms.

Air & Water Reactions	Sensitive to prolonged exposure to air and darkens on exposure to light. Insoluble in water.

Reactivity Profile	2-Chloroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents.

Fire Hazard	2-Chloroaniline is combustible.

Purification Methods	Free it from small amounts of the p-isomer by dissolving in one equivalent of H2SO4 and steam distilling. The p-isomer remains behind as the sulfate. [Sidgwick & Rubie J Chem Soc 1013 1921.] An alternative method is to dissolve it in warm 10% HCl (11mL/g of amine) and on cooling, o-chloroaniline hydrochloride separates out. The latter can be recrystallised until the acetyl derivative has a constant melting point (m 90o). (In this way, yields are better than via the recrystallisation of the picrate from EtOH or of the acetyl derivative from pet ether.) [King & Orton J Chem Soc 1377 1911]. [Beilstein 12 III 1281, 12 IV 1115.]
