摘要
The present invention relates to a method for manufacturing sodium bicarbonate through carbonation of an alcohol-water mixed aqueous solution in which sodium hydroxide is dissolved. More specifically, the present invention provides a method for manufacturing a sodium bicarbonate (NaHCO_3) (wherein R is a C_1 to C_4 linear or branched alkyl group) comprising steps of: dissolving hydroxide in a mixed aqueous solution of alcohol (ROH) and water to manufacture a mixed aqueous solution in which sodium hydroxide is dissolved; injecting a mixed gas of carbon dioxide and nitrogen into the mixed aqueous solution in which the sodium hydroxide is dissolved and conducting a reaction thereof; and filtering, separating, and drying a product obtained by the reaction.
