N -nitrosodiphenylamine is a chemical compound from the group of nitrosamines .

Extraction and presentation

N -nitrosodiphenylamine can be obtained by reacting nitrous acid with diphenylamine .

properties

N -nitrosodiphenylamine is a flammable, difficult to ignite, crystalline, green solid that is very sparingly soluble in water. The heat of decomposition determined by DSC is −129 kJ · mol ⁻¹ or −650 kJ · kg ⁻¹ .

use

N -nitrosodiphenylamine is used for the heat stabilization of plastics.

safety instructions

Oral administration of N- nitrosodiphenylamine leads to transitional cell carcinomas of the urinary bladder in male and female rats and to fibromas of the skin and subcutaneous tissue in male rats . These tumors are not observed in mice.
