FIELD: chemistry.
SUBSTANCE: monoethanolamine, formaldehyde or paraformaldehyde, taken in the molar ratio 12, are mixed and: dispersed in a hydrodynamic acoustic apparatus with a frequency of 7.2 kHz per flow at a temperature of 15-70°C without a catalyst.
EFFECT: increased absorption capacity, selectivity in terms of hydrogen sulfide and mercaptans agents, absorbency, reduced process time and reduced energy consumption.
