Abstract (English):
Examination of the structure of surfactant-water microemulsions with a linear dimension of 1-3 microns by infrared spectroscopy showed that the molecules of sodium oleate dissociated on positively charged Na+ ions and negatively charged anions. It was found that anions formed hydrogen bonds with the molecules of H2O. This results in the reduction of dissociation energy of hydrogen bonds between water molecules and, therefore, reduce energy evaporation, reducing the output of nitrogen oxides in diesel engines.
