摘要：

Experimental studies of the mechanism of surface ionization of amines on the surface of a microalloyed molybdenum alloy in the air at atmospheric pressure were performed. The products of surface ionization of triethanolamine, Dimedrol, and papaverine were studied using a high-resolution mass spectrometer. The physicochemical parameters of surface ionization of some organic nitrogen compounds were measured. It was shown experimentally that the ionization of organic compounds of this type on the surface of the heated molybdenum alloy in air at atmospheric pressure occurs by a mechanism involving Bronsted sites (Bronsted).
