CAS RN:107-13-1

Toxic Combustion Products

Combustion by-products include hydrogen cyanide and oxides of nitrogens.
Lopac, an acrylonitrile polymer, produces ammonia at pyrolysis temp of 188 deg C and above. At temp 500-740 deg C products are carbon monoxide, carbon dioxide, acetylene, ammonia, hydrogen cyanide, acetonitrile, acrylonitrile, propionitrile and pyrrole.
1 kg of polyacrylonitrile plastic produces 15 g hydrogen cyanide upon heating; so in a 30 cu m room 100-200 g polyacrylonitrile fibers yields 10-15 times the Maximum Acceptable Concentration value.
