  Active ingredients containing fluorinated organic compounds such as
Fluoroalkylamines or pyrimidine-based molecules are promising in the field of
agriculture (pesticides and herbicides) and pharmacology (antibiotics). The
massive use of these molecules will result in a massive increase in waste
containing this type of molecule. Developed countries have restrictive waste
management policies, which is not the case in developing countries. In the
latter, we are witnessing a proliferation of storage areas and open-air
disposal of waste, sometimes from developed countries. These practices have
enormous consequences on the environment such as air, soil and water pollution
and therefore on human health. One of the solutions already proven on solid
waste would be the use of plasma torches. These torches can reach high
temperatures (5,000 K to 20,000 K). However, the use of these means of
treatment is not without danger since toxic or lethal molecules could be
produced. In order to understand these difficulties, we propose to study the
influence of air on the chemical composition of a plasma based on
fluoroalkylamines (trifluoroethylamine: C2H4F3N, nonafluoropentylamine:
C5H4F9N, etc.), at atmospheric pressure and at atmospheric pressure. local
thermodynamic equilibrium (E.T.L), in a temperature range from 500 K to 20,000
K. In order to obtain the chemical composition of the plasma, we use the Gibbs
free energy minimization method. The results obtained show that dangerous and
toxic gaseous chemical species such as CF2, CO, HCN and HF appear at low
temperatures with high concentration.
