Khoma R. Acid-base interaction and sulfooxidation at chemosorption of sulfur dioxide by alkylamines aqueous solutions.

The dissertation is devoted to the study of physico-chemical processes in the interaction of sulfur dioxide with alkylamines and their derivatives in aqueous solutions, depending on organic base structure, temperature and the presence of O2. 20 ammonium sulfur-containing oxyanions salts and three van der Waals clathrates were synthesized for the first time. X-ray diffraction analysis was performed and the structure of 23 compounds were established. A new method for the sulfamic acid synthesis has been developed. New methods for aminomethanesulfonic acid (AMSA) and its N-alkylated derivatives synthesis have been offered. 5 new N-alkylated AMSA derivatives were synthesized by the original method. The developed import-substituting SO2 impregnated fibrous chemical sorbents are introduced in practice and are used for the manufacture of gas-mask elements of lightweight gas-dust respirators.
