Investigation to the formation of nitrosamines during production and storage of elastomeres .3. Kinetic aspects of nitrosamine formation in the gas phase
The nitrosation of typical rubber amines by NO2 was investigated in the gas phase. In every case the corresponding nitrosamines were formed at a moderate rate. The shorter the alkyl group of the amin the faster occurs the formation of the corresponding nitrosamine. Before the nitrosation takes place an equilibrium of dimerization between NO2 and N2O4 exists. As a consequence of this, a negative energy of activation for the whole reaction results.
