FIELD: chemistry.SUBSTANCE: invention can be used in inorganic chemistry, medicine and microbiology. Method of obtaining sodium hydrocarbonate, which contains stable isotopeC, includes interaction of sodium hydroxide withCOin solution with heating at excessive pressure. Process from the beginning to the end is carried out in water medium under pressure not more than 1 atm at temperature 70-80°C.EFFECT: invention makes it possible to obtain target product with output up to 97,8%, with isotope purity not less than 98%, and reduce loss of initialCO.6 ex |
