Химические свойства
Light yellow oily liquid with have characteristic amine (fishy) odors. soluble in alcohol, ether, benzene and dilute acid, slightly soluble in water. Anisidine exists as ortho-, meta-, and paraisomers.
Использование
m-Anisidine is a highly poisonous monosubstituted aniline used as corrosion inhibitorsfor aluminum, copper and other metals in acidic solutions.
прикладной
m-Anisidine is used in:
The synthesis of N-substituted-3-chloro-2-azetidinones, which are potential anthelmintic agents.
Rhodium-catalyzed synthesis of indoles and copper-catalyzed synthesis of benzimidazoles.
In the preparation of azocalix[4]arene dyes.
Общее описание
M-anisidine appears as pale yellow oily liquid or dark red liquid. (NTP, 1992)

Методы очистки
o-Isomer impurity can be removed by steam distillation. Another possible impurity is the precursor 3-nitroanisole which can be removed as for the preceding o-isomer and fractionating using an efficient column. It is a yellow liquid.

Утилизация отходов
Dissolve in combustible solvent
(alcohols, benzene, etc.) and spray solution into furnace
equipped with afterburner and scrubber, or burn spill
residue on sand and soda ash absorbent in a furnace.
