Properties and stability
1. It is toxic and may cause irreversible damage to the body. Appropriate protective clothing should be worn when used in large quantities.
2. Exist in smoke.
Storage method
Stored sealed and protected from light.
Synthesis method
Using o-nitrobiphenyl as raw material, obtained by reduction: reflux o-nitrobiphenyl, ethanol, and stannous chloride in a water bath for 3 hours, recover the ethanol, cool the residue, and add 40% liquid alkali to make it Strongly alkaline, separate the oil layer, extract the water layer with ether, dry the extract with anhydrous calcium chloride, filter to recover the ether, wash with ethanol to obtain the crude product, and then distill the crude product under reduced pressure to obtain the finished product.
Purpose
1. Used as raw materials for organic synthesis. Manufacture of carbazole resin and synthetic rubber. Cancer research.
