Properties and stability

Avoid contact with strong oxidizing agents.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

Mix 40% formaldehyde solution, sodium cyanide aqueous solution and aniline, then add ethanol to make a uniform solution. When this solution is heated, it reacts violently with the production of ammonia gas. When the reaction solution no longer produces ammonia gas, the ethanol is distilled off and the precipitate is precipitated with acid. Filter and recrystallize with dilute ethanol to obtain pure N-anilinoacetic acid.

Purpose

Used for colorimetric determination of copper, intermediates for manufacturing indigo, and also used in biochemical research.
