INVESTIGATION ON THE FORMATION OF NITROSA MINES DURING PRODUCTION ANDON STORAGE OF ELASTOMERS

The nitrosation of gaseous diethylamine through NO2 was investigated. It was shown that this reaction has a radical character. The rate of r eaction in the dark as well as in the sunlight is high (k = 6,0 +/- 0, 6 . 10(8) l2/mol2 . s at room temperature). It is worth mentioning tha t N2O4 and not NO2 is the direct nitrosating agent. Before the nitrosa tion takes place an equilibrium of dimerization between NO2 and N2O4 e xists. As a consequence of this, a negative energy of activation for t he whole reaction results.
