FIELD: chemistry.
SUBSTANCE: invention relates to the chemistry of chelating agents, specifically to the use of compounds based on amides of amino acids and ethylenediaminetetraacetic acid of general formula (I), where R is selected from I-1, I-2, I-3 and I-7, as carbon dioxide hydrate formation promoters.
EFFECT: compounds can be used in trapping carbon dioxide and separating gases. 1 cl, 2 dwg, 1 ex
